EDIT: I decided to add this because I know 8 pages is a lot of time reading and I share a ton of longer posts.

If I can go from literally 0 knowledge about welding to being able to weld in all positions, with just about every process in a few years you can to. It's not for everyone, the pay isn't as great as its made out to be for the majority, the hours are long but it is rewarding and can elevate your life if you need a career path and don't know what you want to do or don't have a useful skill or aren't suited for the office life. The thread ahead details my personal journey, I try and share what knowledge I gained along with personal stories and tips I learned and a ton of pictures. Please feel free to ask any questions you have, and any criticisms are also welcome.

Enjoy.

So I had a thread in GD a while back, before I realized there was a specific forum for metal working so I'll post a link to that if I can find it, but I'll also share a lot of what was in it. This is gonna be a long thread, but there are a bunch of pictures if you just wanna look at that.

To start off, I am no expert by any stretch of the imagination.

I settled on a trade because I liked the fact that trades are always hiring, and they pay pretty decent. I know a bunch of guys who went the machining route, but math is not my strong suit so I looked elsewhere. I settled on welding because I'm good with my hands, and the idea of melting metal sounded cool. Never welded in my life, and had no clue going in what I was in for.

So in late 2017 I had finally saved up enough to put myself through school, and I signed up for "Welding 101" which is an 8 week course. Started in August and being a moron, I did not realize at the time it was only 8 weeks so that was the only class I ended up taking that semester even though it ended in October. I learned the basics like brazing, and basic intro's into Arc Welding and Mig. We learned oxy acetylene welding first, and started the very first night which over 1/2 of the class was entirely unprepared for. I think me and one other guy had actually followed the syllabus and gotten all the gear, and welding rods. I fucking sucked at Oxy. It just did not sink in, and we had a short lecture and would spend most of the time in the lab welding. I don't have any pictures of the terrible welds, but you can probably google "shitty oxy acetylene welds" and find what my labs were looking like. But I tried, I stayed as late as I could, and just kept trying.

We moved on to stick, and after hours of trial and error and a ton of stuck rods (the first few plates looked like a punji trap) it finally started clicking and I started getting the hang of it. However it still didn't look anything like what the other classes were turning in and especially not what my teacher was doing for examples. So after class I started Youtubing "stick welding basic tips" and "what not to do when stick welding" This video in particular was very helpful because he specifically did it wrong, and his bad welds looked like my best welds and I realized what I was doing wrong.

I specifically was going to slow while long arcing, with a bad drag angle and not cleaning my welds enough and was getting a bunch of slag entrapment's and porosity.

But by the end of the class, I had gotten Arc welding down pretty good but not great. This was my final. Just a basic butt, lap and T joint. We had a choice of Arc or Mig and most of the class chose Mig. I however spent so much time trying to master Arc I sucked really bad at mig and chose Arc. (some pictures are edited because we had to sign our names)

So that was the end of Welding 101 for me. Finished with an A.

Interesting things I did not expect: The amount of actual homework. It's not just lab work, there was a decent amount of homework (quizzes and review questions) and a midterm and a final both written and in the lab. The other cost's besides the class, the class at a community college is around 400 give or take but you also need to plan on paying another 150 for the book. Welding: Principles and applications 8th edition but it's used in all the classes. Then plan on a few hundred more getting a good helmet, a welding jacket and some electrodes. Buy a better helmet, because the 40$ helmets at harbor freight or Northern will work, but you will eventually hate it and wish you had just gotten the better helmet to begin with. I know I do.



So the next class I took in the spring semester of this year was Welding 123. This is a further introduction into Arc welding, and you learn a lot more about how to make good welds, and the more technical sides of arc welding. I had a great teacher for this one, who spent about an hour and 20 mins lecturing and then we went to the lab for another 3 hours. The homework was exhausting and sometimes mind numbing but it helps. But the lab work is where you really get to learn by trial and error. He spent a ton of time explain everything, and would show you what you were doing wrong. But if you were doing well, and had a decent handle on things you were left to your own devices to complete your assignments and whatever else you decide to create. What I really liked about this was I was able to hammer out the basic assignments in 30 minutes, and then I would just start welding a bunch of different stuff so I could combine stuff like an outside corner, with a T joint on a Butt joint that had a lap. We also did a lot of cladding

Heres a few projects I did. Again I didn't really take many pictures





First time using 6010, and I hated it. I thought my electrodes were fucked up since it was splattering everywhere and burning.


This was the "fill the trough" assignment. We basically had to stack the welds, making sure not to leave any undercut and absolutely no slag inclusions. There was a cut test as well. Most people were only able to get about halfway up before we ran out of time as we had other things to do that night, and as you know when your stacking a weld it heats up affecting the metal and weld so you have to give it time to cool. I was the only one to pass with no slag inclusions. The only woman in our class, for some reason just kept welding over the slag and she had massive cavitys of slag inside. It was a 50/50 weld to slag ratio





And for the final we were given a timed project, which had to be welded in specific areas and not others, and had to generally be of a nice looking weld or you were supposed to grind it off and start over. You had 6 coupons (the metal strips) and that was it.

Here's mine. You can see 7024's in a few pictures be we had to use 7018's. (In fact I have yet to use one). I also fucked up with by welding the butt joints in the wrong direction, but the class for the most part showed up, slapped together the project as fast as possible and were out in under 20 mins and you can see the results. I don't even think he noticed mine was the wrong way.




Here's the part of the class.


The woman that was previously mentioned, turned in this. Teacher had a hilarious face. She was actually proud of this, and seriously thought she was going to get an A in the class.

Was your welding all flat or did you do vertical and overhead? If you do vertical weld , do you start at the bottom and go up or do you downhand?

So that was the end of 123. Finished with a 102 on my Midterm and an A. (I was a C student when I went to college for Business Admin)

What surprised me with that class was the lack of effort by a large majority of the class. Class was 5:30 until 9:30 and after you got the lab done you could leave, but it was strongly suggested that you stay until the end practicing. Only one other guy would stay with me until 9:30 with the majority rolling out at 7:00 which was around 30 mins after we got to the lab. The quizzes are all open book, and getting less than 90% if just fucking lazy. We also had review questions on every chapter, and if the overall class average was not 80% we would have to take a written exam on top of the project. We had 5 weeks to turn in like 5 quizzes and 6 chapters worth of review questions (around 20 questions in each) and SOMEHOW the majority of the class was getting 70% or less on open book quizzes and wouldn't turn in the review shit. After getting extension after extension it came down to one dumbfuck who only had to turn in the quizzes by the end of the 7th week and we wouldn't have to take another written test. On the last day he showed up late, didnt have them done and someone finally just let him copy theirs so we wouldn't have to do the final.

Don't expect people to be any different than any other college class. The people who are going to better themselves will put in the work to do it. The fresh out of Highschoolers and the people who are fulfilling an obligation to get FAFSA money, are going to be the the anchors of the class. The other guy who put in the work with me, was a convict who had just gotten out after 7 years. He knew that he had to be the best applicant to have a shot at being hired anywhere, so he put in the time and effort to learn the material.

The next class which was also this spring was Welding 160, Mig.

Same teacher as 123, and unfortunately a bunch of the same social rejects from that class as well. I had very little experience with Mig, and it was a huge difference from Arc but after a bunch of trial and error I finally got a basic understanding of it. After the hour lecture we would immediately go and disassemble the welder, and reassemble it. Every night we did this. Same problems as before, a couple would stay until class actually ended but most were out the door by 7. Same problems with homework as well.

Here's some of the work. I hated Mig at first, but I grew to really enjoy it as the class went on.

We did a bunch of stuff, and I tried to get some pics of some of it but the basic butt, lap, T and outside corners were the basis of every project. Some of the more interesting stuff we did were making towers, which were then water tested. (Tower will look like the pipe below, only with four outside corners, welded to a butt plate) If it leaked, you redid it. I again didn't get a ton of pics, but here's a few

This was the first pipe we did, and after passing the water test I decided to weld up another butt joint, then cut it in half and weld it to the top, and then grind it down. I added a second pipe section as well and ground that down as well for fun. It is still waterproof and sat in water for around 20 mins and didn't fill up






This was the first time we had to make a vertical stacked weld.



First time welding aluminum. It did not weld like I thought it would


And a nice little shelf we made as our final. It was the easiest so far, and the point was to show that you don't always need to do full welds, sometimes tacks work just fine. Finished out with an A

So far in the classes I have done, we have only done flat welds, vertical and horizontal. No overhead yet.

The method varies depending on what your welding. If you are stick welding it's vertical up, which allows the metal to pool as you go. Mig can depend on if your using Flux core, or solid wire and can be both vertical up, and vertical down. The general rule is if there is slag you drag so you would do vertical up, and if your using solid wire on thinner metal you vertical down. If it's thicker you can vertical up which allows it to penetrate deeper

And finally this fall they rearanged classes and what was offered and required to graduate with a full cert, and it fucked me over a bit. I had planned on doing ARC 124 and Tig but the Tig class was moved to spring, and 124 was only offered in the 2nd 8 weeks of the semester. So I had to wait until this week, and am now taking Arc 124 and Welding Blueprint reading.

The blueprint reading is pretty self explanatory, but a side note I had to get a second book for this class. It's the only other textbook you have to get in this program, but is also 100. Arc 124 is where we will now be doing everything in out of position welds, vertical, horizontal and overhead. It's the last Arc class before I'll be doing a set of classes on qualifications.

So to graduate I still have to do:

WEL 130 Inert Gas Welding
WEL 141 Welder Qualification Test I
WEL 142 Welder Qualification Test II
MAC 146 Metals/Heat Treatment
WEL 145 Welding Metallurgy

And I'll also end up doing Pipe welding which is no longer required but I think I want to do it anyways, and Mig 220 which is advanced and focuses on flux core and pipe welding with mig.

So had my first class tonight in 124. Finally everyone but one guy showed up ready to weld. Teacher is no bs, and focuses on welding in the lab over reading the book which I like,  though the same quizzes and written mid term will still happen. The class was informed that the class is from 5:15 until 9:25. Don't leave early under any circumstance and that we were there to weld. Which we did. Tonight was just a bit of cladding to show him our welds, so he can help us developed our skills. It was 4 hours of straight welding, no stop. (shitty time to have a pulled mussel in my back lol)

We did two kinds of cladding horizontally. The first we basically just laid stringers spaced apart so he could see the individual stringers on a butt plate. The second we stacked welds in a normal cladding with all sides up to the edge welded.

Here's one that I took a pic of.



I was kinda pissed after I realized that my electrodes had some moisture in them, and it caused a few wormholes. He recommended we all stop using shitty northern tool electrodes and go get some Lincoln Excalibur and gave me a handful. They were noticeably better.

So ya, if your interested in this I'll keep updating it with pictures and what were doing. If not, that's cool too just say so and I'll stop posting stuff. If you have questions about going to school I'll try my best to answer and if you really want, I can also post stuff like the quizzes so you can brush up or learn something new.

If you continue with stick welding make a hot box to store them in, just a lightbulb will do. ( If you have some that you think may be damp a toaster oven will fix them in a jif.)
Makes a huge difference and yea stay away from HF electrodes.

A friend in my car club at the time was a welding instructor at a community college.  He came to my house and taught me how to weld with my equipment.  Luckily, I bought the Miller buzz box, much better than the tombstone Lincoln.  I loved me some 7018 rod and burned a lot of it.  I haven't stick welded since the 90's.  All I do is gas cut, plasma cut, and Mig these days.

Cool thread.

I'm an electrician, but took some welding classes at the local community college just for myself. You're right on about the guys that want to just do the minimum. I will say though, that our classes were much more class room focused than lab. We covered metallurgy, prep, filler selection, weld theory, etc. It was good since the actual welding part is really the easy part, on the other hand, troubleshooting when you run into issues is important too and we missed out on a lot of that. I took a break and have just been welding at home for the last year , so I plan to start back up in the spring semester. I think that's the best way to go if you can swing it. Get the basics down, use what you learned, then go back and learn some more. Being able to apply what I learned helped a lot more than just doing a bunch of coupons.  Not saying that doesn't work, but bouncing around between different welds helps the information stick for me.

NovaLabs/Makers in Reston has Mig and Tig and will teach intro safety classes.  Once you've been signed off on the tools, your free to use it without supervision.  Not certification classes, but people have used the lab to practice to get certified.  Full Disclosure:  I'm the backup Mig instructor and working on Tig classes.

PM me if you want more info.

Oh man that's pretty awesome. I'm about 4 hours south of you. I think my school has some open welding nights but I'm not entirely sure.

So here's tonights update. Yesterday I had Blueprint reading which has so far been the only class I really hate, and unless someone really want's to see the assigned homework I probably won't post much concerning that as it's very text book oriented.

Tonight in Advanced Arc (124) we watched a video detailing some stuff with vertical and horizontal welding, which I'll try and find and post. Then we did some more basic cladding only it was all done horizontally and vertically. We always switch machines so you have to use a different machine every time (every machine is different and welds differently) and I got a finicky one tonight. It mechanically worked fine, but it was just not welding like it should have been so some of my work wasn't up to my own personal standards. Other problem I had was my electrodes.

I implore you, if you are serious about Arc welding to get Lincoln Excalibur 7018's as they are worlds better than the shit ass Hobart rods I was using. My teacher gave me a handful last time, but I only had 5 or so of those left. So tonight I was using mainly my Hobart electrodes and they just were not working like I wanted them too, with the slag not breaking uniformly and the rods burning at an uneven rate. I could always tell when I got one of the Lincon rods, because the slag came off in one piece and laid down perfectly.

I also had a bit of a problem with fatigue, and not being able to see very well. Because I couldn't see very well my lines would be fine for about 75% of the way, and then would start dropping down causing it to bulge. I'll highlight the areas that were problematic in the later pictures.

I did however remember to take pictures for you guys throughout the night.




Horizontal cladding finished.


Vertical

Part of being a student is not knowing what I don't know, so if I missed something don't be afraid to say so because I can't learn from a mistake I didn't notice.

Here's some stuff I noticed just looking at a few of the pictures. Overall I'm not terribly upset that it didn't come out as nice as normal, because this is only the 2nd time I have vertical welded (did if for maybe 30 mins last thurs). Eventually I'll be able to get the drag angles right the first time, and won't have as many problems with bulging.



So I highlighted the slag on this, to show you just how irritating the Hobart electrodes can be. Even though the weld was fine, the slag did not break clean and required a fair amount of chipping. This picture was actually taken after being chipped, and cleaned with a wirebrush. Even after that there were still pockets of slag that had not come off. If you neglect this, you will have problems. The second part, is a bunch of red lines. This is an example of what I was talking about with not being able to see well. When you have a shit helmet, you can't see shit. So for myself, I would lay a great bead that followed the previous line pretty well. Only problem was the previous line was not straight which leads you to having crooked lines.


This is what Slag should do, and what it does when I use the nicer Lincoln electrodes.

This is another example of electrode problems. The biggest problem I was having on the vertical was the starts. Using the shitty Hobart rods I was having a problem getting them started, and having to pretty much scratch start and that was causing me to stick them, which required breaking them off, and when you do that, you make a small hill. Do that enough and you get a bulging start. I just could not get those electrodes to start worth a fuck, and it showed. Once I got it going it wasn't too bad at all but almost all the starts suck.

Thanks man. Ya we have a range of people who take the class, and in my first one there were a couple guys who just wanted to get a basic understanding on welding so they could do simply projects at home.

Even in this class, the younger guys just out of HS are the ones who are mad that they have to stay until the end of class. I took like 3 smoke breaks in the 3 hours in the lab and there were always 4 or 5 guys standing around on their phones bitching about having to stay.

I should also clarify that in the previous classes, there was a good amount of classroom lecture and book work. I would say in the 8 weeks we had around 7 quizzes, and a usually 80 question mid term. We had to obviously learn the safty stuff, but in each class there were a good deal of lecture on how to deal with setting up the welders, stuff like explain the differences in DC and AC and all that, and the causes and effects of arc blow, long arcing and all that.

This is the first class that we have had around 30 mins of lecture, and then straight to the lab. I like it that way personally because I am very hands on. I can read something a million times but until I do it myself, it doesn't sink in.

Oh and I just found a few more pics of a project I did for fun in my Mig Class. It was similar to the assigned project which I had already finished, but I wanted to practices stacking beads so I took it a bit further. I used quarter inch coupons which required multiple passes to get proper fusion.

I am however very proud of my butt joint, as it is textbook

I saw your thread on making the anvil, and from what I could see it looked like your welding was already really good. But it never hurts to take a few classes if you have the time and money.

Nothing to really report today, Blueprint reading was as boring as usual but I was pretty irritated because we had 14+ pages of homework to do from Monday to Today. I was still working on them at work today, and we all found out from our teacher it's because she want's to go to a casino for the entire week of Thanksgiving. So were rushing through stuff so we won't have to come to class at all that week

Between work, and my other class the amount of take home stuff was kinda outrageous. But I will be picking up 5lbs of the Lincoln Electrodes tomorrow, and I'll include the price if anyone is interested.

Nice! Learning is occurring! That's always good to see.

Definitely agree with getting good electrodes. Shit electrodes are just frustrating, especially starts. Start your arc strike further ahead than the start of the plate, further ahead than you think until you get really consistent with starting up, and move back. Arc strikes will leave you busting a test, so get used to keeping your arc strikes ahead, long arc it a bit back to where you want the bead to start, and move forward from there. If you can swing a cheap used vertical rod oven off youtube, grab one for low hydrogen stuff (7018). The "lightbulb in a pipe" thing doesn't get hot enough. A 60 watt lightbulb isn't gonna get the oven to 300-350 degrees.

Downhill 6010 is super common in pipe welding, so practice that as well. 7018 uphill is common, but anyone who says you can't weld stick downhill is just wrong, and there are definitely times where it's preferable and even called for in the WPS.

Something that always helped me with keeping stringers straight, do your first one right on the edge of your coupon so you have a known straight line to follow. For every subsequent stringer, provided your bead width is consistent, use the toe of the previous weld as your "straight" line. Trying to stack beads next to each other always had me screwing up. Since tests will want a certain amount of overlap on your fill and cap passes, it pays to get used to using the toes of your previous beads as your reference. Obviously you've gotta do whatever your instructor wants for the lab, but for practice, definitely train like you're gonna fight. And while you're learning, don't hesitate to take a straight edge and your soap stone or scribe and mark a straight line to follow. Every little bit helps when you're learning.

Jody Collier has probably some of the best welding videos on youtube. That, "enough amperage to hold a tight arc, then hold a tight arc" that he's always preaching really is the best thing you can do on stick. Weldtube is pretty alright too, Hjalmar Aguilo talks too much and his videos are way too long, but there's good information. I have trouble listening to Bob Moffat from Weld.com but he knows his stuff if you have the patience to listen to him kind of drone on. Don't bother with the "Mr. Tig" weld.com videos. Dude is clownshoes. Jacob Schofield has some good pipeline videos. He's hard to follow sometimes but there's good info to take as well. He also shoots, which is always good to see.

If you are able, bring a grinder with a brush wheel on it as well as a rock disc and flapper wheel. Makes getting rid of slag SUPER easy, gets you back to burning rod faster, which in turn means more practice, and better welds. I always have at least 3 grinders at the ready, one with each type of wheel. Not having to swap wheels while you're working is great. And ALWAYS GRIND YOUR STARTS!!!! Good job picking up a nice hood. It definitely helps lots. I've got a fantastic Optrel that's amazing indoors. It will do everything from low amperage tig to hot and heavy stick. It drives me NUTS outside if the sun is behind me. There's JUUUUUST enough light leak reflection that it messes with me. Outside I use a Wendy's Pancake with an ArcOne singles. Not the cheapest solution, but the best thing I've found for welding outside, and I don't need to be able to weld low amperage tig so the shade 10 is perfect for pretty much everything else. Pick up a set of cheaters if you want too, it brings the work closer without having to stick your head in it, even if you don't need glasses.

Doing great man, keep up the good work! Welding is a fantastic skill to have, even if it never becomes a profession. And as much as the blueprint reading is a pain, it's a necessary evil, and the better you are at it, the faster you can work, and the more accurate your work will be.

Alright guys, it's thursday so I'll get right to it.

Tonight our teacher had to leave early so he gave us some time consuming projects to make sure everyone stayed until the end of class. We were supposed to make 3 troughs, one flat, one horizontal and one Vertical. I don't think anyone actually got all 3 done, as this process is very time consuming. We are also going to be cutting them on Tuesday, and any that had slag inclusions would have to be redone. So I personally looked at it like I would rather do it right the first time, then rush and do 3 shitty ones just to complete it all tonight. I'm sure I'll here about it Tuesday, but I just can't half ass cut tests because I hate having defects present once you do the cut. So I take my time, do it right the first.

I will however be picking up a grinder, as I hate having to walk across the shop to wait in line to wire-brush my welds and that takes up a bunch of time even when I don't use it to clean every weld.

I also bought the Lincoln electrodes, and they came to around 40 bucks for 10lbs and it was worth every penny. Every problem I was having on Tuesday was fixed and they just work so much better than the shitty Hobart rods. You'll be able to tell just by looking at the pictures how much better and more uniform the welds are tonight.

I also made an effort to take more pictures, so be prepared for a pic heavy couple posts.

Root pass, notice the interesting hole that burned into coupon. Turns out I found the machine that was having problems and after switching booths I did not have any other problems like this.






This is an outside corner, but I had to restart about mid way through and it cause me to mess up slightly

This is going to be a great example of what I personally strive for and why it can take me longer to finish projects.

While waiting for my first trough to cool down some, I went ahead and welded up my next one, and started in on the horizontal. I decided to use a electrode that was a little less than halfway used for my root pass, and that was something I knew I shouldn't do but got in a hurry. It ended about half an inch from the end of the plate. I went back and restarted it, and wire brush cleaned it but I knew there was a slag inclusion in it, as I saw a piece of slag get knocked into the work as I was welding it.

Now I had a choice. We would be cutting it about 2 inches in on each side, and chances are the slag inclusion would never been noticed.

Highlighted the restart (still working on my restarts, as its something I'm just not great at.


But I knew it was there.



The new root





Sometimes you fuck up, it happens but if you chose to ignore a problem because it will take too long to fix, or you don't want to get yelled at then you are asking for trouble. I don't want to be the guy that half asses shit so I will grind out my work if I think there may even be a 1% chance of a problem.

This is slightly deceiving, as it looks like there are a ton of small holes in the freshly grinded metal, but its actually dust partials







And this is where I stopped for tonight on this one, because I wanted to work on my horizontal more as it was getting to be around 830ish. I was really focused on getting as much done on this next one as I could, so I didn't take many pictures. I'll be sure and grab a bunch of the finished work Tuesday, as well as the results of the cut test

OK so it's Tuesday, and that means welding time.

Tonight was somewhat irritating, because our teacher was out for the entire class tonight so we had to wait until the other teacher finished his lecture to open the shop up for us. So we didn't get inside until 6:45ish. We were just working on the same project as last Thursday. My phone is aving some serious battery problems, so I was unable to take many pictures tonight as it kept dying and I was having to charge it in the booth. I was also pressed for time. I will have all three done by Thursday, but these troughs take a considerable amount of time to do, so I'm looking forward to doing the cuts and seeing just how well I did.

I have been taking a bit longer to do these, because I am shooting for welds that would pass a qualification test, and I don't want any slag inclusions so I'm being very careful to thoroughly clean the work before each weld. A fair number of the class is trying to get by with doing as little as possible, and in particular they made their troughs as narrow was possible so it would require less time, and fewer passes. I took a picture of one of the other guys who is actually doing it correctly (and his look really good), and It also got another of the guys who is trying to do as little as possible and you'll see what I'm talking about.

I'll include a quick paintshop of how I was taught to make the trough, in case anyone want's to try their hand at it for fun.

This is the correct way to make one. You weld the outside corner first (the bottom of the V) first, and then you tack both ends to the plate. We were taught that you should try and shoot for a 90* angle as best as you can, and to use anther coupon as a test piece to make sure you got it right. After making your initial tacks, you use a 3rd piece to check and see if your at a 90* and if the coupon firs flush, your good and you weld. If it doesn't then you either hammer it apart or together until your as close as you can get. Then you flip it upside down, weld down the outside corner, flip it back over and weld it to the base plate.

And this is what a bunch of the younger students are making. I don't really get the point in doing this, because before we even started he specifically told them not to make them too narrow, and if you did you would be re-doing them all
.
Attachment Attached File



Anyways here's a few from tonight, not in any particular order.

Horizontal. I ground some off as one side was getting a bit higher than the other.



First pass after coming back today on my flat position trough.



Same thing, got a little higher on one side so I evened it out some.







I thought about ending it here, and this was going to be the final reveal but after I got done I was talking to my old teacher, and he suggested doing one final cover pass because one side is slightly lower than the other. I could have left it, but I decided on Thursday I'm going to do a new cover pass.



I took a picture of it cleaned off, but of course my phone died while taking it so it didn't save correctly. It came out looking really great, but I'll end up doing one final line almost completely across just to eliminate the slight decline on one side. I think it was getting up there in the number of passes that I ended up making, and I would assume there was no less than 50 in this one piece alone. So many electrodes



And this is the "homework" table, just laying everything out to be graded. I'll highlight what I was referring to and where mine are in the next photo.

Nice work and congrats on the class! great pics too

I took a gsmaw class a long time ago. Mine was every Saturday for 3 months 7am-1pm. People would finish the project and leave. Instructor would just shake his head. People who wanted to stay could, outstanding students were allowed/encouraged to take union welding test. Instructor was a retired Nuclear Welding Inspector. The more rods you burn the better you get. I would stay the entire time I figured I was paying for it might as well.

I would leave and go straight to work, I was the "welder" at my job and once I got my certificate that is primarily all I did. I self-taught myself vertical and overhead by just doing. I was teaching myself TIG as well and doing real well. MIG was difficult because you could never get the gun set up right, and once you did someone would fuck it all up. So I just let others MIG. We used cover gas so they would made birdshit and grind it down. Boss was willing to buy whatever tools I needed. We had a lot of nice equipment multiple MIG and TIG, Plasma Torch, all Miller. I carried a Miller Bobcat in the back of my truck. He welded too but was terrible so he sent me to school. He was a master Electrician.

We built a hot box using a light bulb as someone suggested. It worked great, I had plastic rod box (tube) I would take what I needed for the day and return them to the box after wards. During the summer we would spray them with hairspray to seal out the humidity a trick told to me by my welding instructor. They say doing either isn't a great idea, but when you do not have the option of popping a new tin or box of rods every time you arrive at a jobsite it is the best alternative.

So to sum everything up, I feel like I'm getting better each class but obviously I still have a great deal more to learn. I am however feeling a lot more comfortable with my out of position welding, and especially my horizontals. I have not spent as much time in vertical yet, as these troughs are just taking a ton of time to do, but I'm fairly confident that I'm going to be able to at least have a decent one but it may not be as good looking as the flat and horizontal ones.

It was kinda cool getting to know everyone in the class a little bit better seeing as we had over an hour to kill before we could get into the lab. The guy whose work I highlighted with an arrow on the left side is a really cool dude, and showed us some cool pics of his time in the military.

Another pretty interesting thing I noticed, is even the guys who are just out of high-school are all really into shooting as that was something we all talked about for a while. And surprisingly just about everyone has their own tannerite story's haha. While the rest of the academia is at a race to the bottom, its pretty nice to know that just about everyone I have had classes with has been a definite conservative and almost all have been somehow involved in shooting sports in one way or another. There were even some MAGA hats in my last class, and just about every truck/car/suv that parks where most of us who are going to school for either welding, or machining has NRA, Trump or some other gun related stickers.

Anyways, all that aside the grinder I picked up over the weekend has helped considerably, as I now just use that to wirebrush clean every weld instead of taking the time to chip and then hand brush each weld. It's a definite recommendation if your going to school, or even just recreational welding.

Again, if you have any questions or comments, feel free to ask or whatever. I'm always ready to hear advice or critiques. More to come Thursday

I really appreciate it, it's always hard to tell if anyone is actually interested in this, or I'f I'm just kinda blogging to myself haha.

But ya, the thing a lot of the younger guys (not all and some older ones) fail to realize is that you are only hurting yourself in the long run by taking shortcuts, and not putting forth the effort to actually learn the material. I know a lot of people in not just this program but in the regular community college classes as well use the FISA grant as a free money, and since they are not having to pay a dime to attend, or buy books AND they get a couple grand out of it, they tend to either half ass it, or drop out after a month.

I have noticed that the people who really want to learn, who stay as late as they can and do as much as they can are by and large the guys who are paying out of pocket and coming in directly from work. I know I personally can only afford two classes a semester usually, so I personally take full advantage of every opportunity to use the welders and also to learn as much as I can. I realized very early that it takes me a little while to learn what I'm doing, and I can't just come in and hammer out the lab in an hour and leave, because it won't sink in at all.

I also look at it like I want to know my shit, because I'm eventually going to be out there looking for work as a welder, and If I can't set up the machine, if I can't do a vertical weld or if I don't understand whats wrong with my weld I won't even make it out of the interview let alone get the job.

And to top if off the school was graduating people that had no fucking clue what they were doing, and all the local company's were wondering looking at an applicant from the program very skeptically because they kept getting "graduates" that had no idea how to make even the most basic welds, couldn't turn on a machine and were just embarrassing the school. So I know that going in, the company is probably going to be skeptical and I'm going to have to prove that I know my shit. I personally like being able to weld from 5:45 until 9:30, because I'm only in the lab twice a week, and only for 8 weeks. The more time I spend in there the more I'm going to learn and hopefully the better I get. For the past few classes, there is only one or two other guys who leave when I do at 9:30. The guy whose stuff was to the left of mine (the vet) and another younger guy. I know that even when my welds were shitty, the fact that I was staying late helped my grade considerably.

The teacher I have in this class is actually an owner of a pipe welding company, who actually went to the program director and was like what the fuck are you teaching these kids, they have no clue how to weld. They said well do you think you can do it better, and that's how he got the job.

What really pisses me off is the fuckups who take a spot in class, which is a very limited number of openings and drop out by the third of fourth week. I had to beg the administration to let me in the Arc class I'm in, and the teacher agreed to overload the class to get me in. He was supposed to have 16 or so students, but by tonight there was MAYBE 10 people.

Older folks tend to have a very different attitude towards schooling.  They've decided the opportunity cost is worth what they're going to get out of it, and are there to learn.  Young kids don't even know the term opportunity cost.

I was very jealous of the young Arabs in my Arabic class that were taking it for an easy A.  I was there to get through 101 & 102 so that I could transfer it back to A&M and finish my degree after 20 years.  I suck as a language student and am very proud of my C in Arabic 102.

Well another week down, and I finally got to get some stuff completed. Teacher was back and we found out there would be no mid term, and the class was basically a pass or fail. So down to the good stuff.

Whose ready to see what a ton of work, and what feels like a thousand passes looks like when you slice it in half. Teacher said not to bother finishing my cover pass so I cut it as I left it on Tuesday.

This is it. I was right, and being very careful and making sure that I ground out any flaws paid off. Not a single defect, and I was pretty confidant in this one. I have no doubt that I could have cut it at any point and it would have passed.



This is my horizontal, ground it a bit flatter and went back to filling.



I wanted to fix it and make the cover pass nicer, but our teacher just wanted to see it cut and for me to move on so I left it alone and cut it.



Looks pretty good right? Well as I told you guys, when you make a mistake always grind it out. While this would have passed, the only defect is a pencil lead sized hole in the most critical part. The root. And if you remember, I knew there was a mistake in that, and attempted to correct it, but I did not grind down far enough to fix it. While it would have passed, It bugs the shit out of me.



Start of my vertical pass. I'm somewhat worried about the root in this one, but the teacher wanted me to just fill it up as fast as possible. More on this in a sec.

So I'm a little annoyed by a couple of things. The first and the one that's really getting to me is this teachers, teaching style.

I know every teacher is different, and teaches in their own way, but this teacher really needs to re-evaluate the way hes teaching this class in my opinion. This is supposed to be advanced ARC, the class we have right before we start taking qualifications and where details count. This is why I am personally taking my time, to make good and quality welds and a finished product that I know I put 100% into, and a product I can feel good putting my name on. I'm not cutting corners, I'm welding as we were taught in every other class.

But that's not what he wants.. He told me to stop grinding my welds when I don't like the uniformity, or think there may be a defect. He told us to weld the plate continuously even if its glowing, as he wants the troughs filled up and there are no "too hot" of plates. He then tells me in his next sentence that while there is a temp range on the qualifications, just to weld these hot. I said something like "I get it, but I also want to be able to pass a qualification test, so I treat these as if I am welding to pass one" and he then asks me if I quenched them. I replied I hadn't, and that we were taught never to water quench because it affects the metal. I had let it cool outside under the fan for a few minutes. He jokingly said something like I would fire you for taking to long or something like that.

I don't fucking get it. In every other class we have been taught one thing, and hes basically telling us to throw all that out and for lack of a better term, weld as fast as possible and let whatever happens happen. So I did it his way on my vertical, and basically just continuously welded no matter how hot, how shitty the beads started to look and how I think its going to turn out.

Anyways, I just don't personally see the point in half assing something, but Its his class. I feel like advanced means we put forth the most effort as possible, and get it right the first time.

And on a funnier note, I was right about the people who tried to cut as many corners as possible. I don't think anyone other than me and the vet passed the cut test. One dude next to me started yelling, cussing and throwing shit in his booth which was pretty damn funny. He had failed every one of the troughs, and was getting pissed because he was having to do all of them over again and even the new ones, after a few passes were getting thrown in the scrap bin and he was told to restart.

So ya, I guess we'll see how it goes, I don't have a personal problem with my teacher or anything like that, it's just the method of teaching this class seems diametrically opposed to every other one.

Also in the real world, its about production, i had a teacher say sometimes it doesn't have to be perfect, just structurally correct. Echo he is saying you've got it, now get it done in one pass.

Thats a pretty fair point. I know I'm not a fast welder by any means, so thats something I really need to work on.

Like I said I didn't take it personally or anything, it was just kinda confusing to have been taught one thing in all the other classes and then be told to do things differently.

It will be interesting to cut the vertical trough for sure. I'm still wire brush cleaning each pass, but I was burning rod in as fast as I could make a pass and clean it. I hope it will be as good as my other work, and if its not it's something I'm gonna have to work on because I do want to get to a point where I can do it right the first time, without having to grind anything out.

Pushing to weld it fast will give you experience with hot steel. It happens sometimes in the real world and you have to know how to deal with it and get the job done.

Welding as a trade covers a huge variety of work.  Most people first think of pipe welding, but that's just a tiny fraction of what's out there.

I've held both structural and pipe certs.  Never actually needed any of them, but they gave me experience.  Spent 3 years repairing heavy machinery and industrial equipment.  Then 10 years on my own doing farm related stuff.

If you're looking to make money, there are two ways to go.  You can specialize and strive to be the best in your field. Or you can get good at everything and never be out of work.  I like to design, build, and fix shit.  So I went the second route and will take whatever is thrown at me. I don't regret that decision one bit.

That's actually what I'm hoping to do eventually. It's why I really took the time to soak up as much as I could in the other classes, because I wanted to be able just about anything using just about any of the different types of welding. I really liked Mig, because its not exactly rocket science to set it up, and you can weld a wide range of stuff.

I'm planning on doing a few extra classes, that are actually not required to graduate. Pipe welding, and flux core,  Advanced Gas Tungsten Arc Welding, visual testing and a couple more.

I figure if I can hold certs in as many things as I can I'll have the best luck getting a really good job.

The thing with certs is that they may help give you a little credibility when applying, but most companies are going to test you themselves.  So practice up.  You need to be good all the time.  Not just on test day.

Experience and hood time is what you need.  I went to a CC two years. First year was spent mostly in the lab 8-3 m-f.  Structural certs with gmaw, fcaw,  and smaw weren't much trouble, but smaw on pipe was giving me fits.  Was only able to pass a few of them.

Second year was spent as a teaching assistant while taking my other classes.  At the end of that, I tried pipe again with the students.  This time I flew through each test like I was born welding pipe.  So get all the hood time you can and stick with it.  It makes a huge difference and is definitely a perishable skill.

So I didn't take a ton of pictures tonight, I was really focusing on getting my stuff done and I have a fucked up Droid, that has a royally fucked up battery and will die instantly at random times especially when I take a picture. It's gotten really bad in the past few weeks, and I'm having to carry a charger with me everywhere because the battery indicator means nothing. So to take pictures I have to have it plugged into the charger and my outlets are full with stuff I actually need (light and grinder) so I'm charging it in the next booth, and grabbing a pic when I can.

So we found out tonight what it's gonna take to pass, and that is a successful bend test on a 3G plate. And that's what he's been wanting us to be able to do, which is why we have been doing the troughs. To move on to the 2g and 3g plates, you had to successfully pass all troughs and be consistent. Weld uniformity and integrity were really important and that's why everyone has been having to redo theirs.

So tonight if you passed vertical up, and cut it with no problems then you could move on to 2g.

I was about halfway done with my vertical trough and was going to finish that out. This was my first vertical trough, and frankly I was not expecting it to turn out well at all. I was expecting several slag inclusions, and since I was using so many of my good electrodes I had started it off using the left over Hobarts that I had from the spring classes. I figured it was going to suck anyways and I might as well be prepared to do it over, and save some of my good electrodes.

Well I go back into it tonight and I thought about what you guys had said, and made the choice to do it as best as I could, and as fast as I could with as little grinding as possible. I also took my teachers advice and welded it hot and didn't grind anything until I was on the cover pass (one side was slightly higher and he said to level it, and do one more pass over it). One thing I had been concerned about was undercut, but he said to just keep getting it and worry about that when you get to the cover, which sounded off to me but I did it anyways.

Turns out he was 100% right. I went in expecting it to be shitty, and it was probably the best one I did (maybe tied with the 1g) but I was shocked.

I was the only one who was able to move on the the 3g which I discovered is much harder in the horizontal position than I had expected. I am really gonna have to work on this one, but it sounds like this is gonna be our focus. I did feel really bad for the guy next to me, he made a beautiful trough, and was really stoked to cut it. He ended up having a single slag inclusion no bigger than a piece of pencil lead but it was pretty deep. He had to restart and make a new one, which he was not happy about (Don't blame em it takes a lot of electrode to do) Hell I'm already down to about 1/4 of the Lincolns and I already need a new wire wheel (the one that came with the grinder was not top of the line by any means)

The other plates you see are scrap I use as an extension so that I don't hit the clamp area and are all removed before cutting.

[#46]
And this is the 3g plate. I'll weld these in the horizontal and then vertical positions. I did'nt take any progress pics because my phone was fucking up more than normal, but I had a rough start to this. I had to add another backing strip to extend it further from the clamps, because I got halfway across on my root pass and my arm started getting stuck on the fucking clamps, so the weld was really fucked up. I had to pretty much grind it all out and restart, and even then it just was not acting how I wanted it to.

Another thing that he had told us was that the rods were going to run out and to plan your restarts. I was having a really hard time with that, and my restarts need a lot of work still. I know this isn't going to be a bend test piece but I really just want to try and get it straightened out so my next one wont suck. Filling the 1/4in root in one pass is a real challenge and its something I'm having trouble with personally. It's much more of a challenge than I had expected. Doing them in the flat position gave me the illusion that it wouldn't be that bad.

So having a bit of trouble sleeping I figured I would watch some welding videos and noticed something on my troughs that I'm actually kinda proud of.

While they are by no means perfect, they are uniform. I took two differant ones, and put them together and was kinda surprised that they actually line up really well and are uniform. Same number of passes and everything

So tonight we watched a couple videos to get us ready for the real meat of the class, the 2g plate test.

Not the video we watched but same principle
Stick Welding Tips- 7018 2g Plate Test


So a lot of the class is still trying to pass the trough tests to move on, but I was working on my 2g plate all night. I knew the one I started Thursday was gonna be fucked up, but I went ahead and finished it off and cut it just for my own information so I could understand what I had done wrong.

I am personally having some trouble with making a clean cover pass in one go, and penetrating the backer strip as you'll see in my cut. I would have done a polish to see how deep it penetrated but I didn't even think of it before chucking it. Not a ton of pics, just some to show you what I'm working on. Biggest problem tonight is the booth I got needed several parts to make the stand actually work and I lost probably 30 mins scrounging parts to lock it in place.

One other guy was doing the 2G plates too, and his were looking incredible. Several are still failing the vertical trough with slag inclusions in the sides about midway up. Overall everyone is doing pretty good even the guys who still haven't mastered it yet because they are trying pretty hard now.



First pass after cleaning out some of the plate.


The cut. Fill looked good with no inclusions but didn't penetrate the base plate really at all.


Working on the second attempt.


Root Pass, I was doing great until I got halfway and had to restart. Still not getting my restarts down very well.

So my phones battery is pretty much done so I'm only able to take a couple of pics since it has to be plugged in to work. I'm really focusing on getting these done so I dont have a ton of time right now, but I did grab a couple of pics, and I did a cut tonight I'll show you guys.

So still working on the 2g plate test, and I finally got one that I was able to cut to be bent. Only problem was, after doing the cut it was a failure at the root pass, for lack of fusion. I was pretty bummed, but I was able to get 2 more started before I ran out of time.



Having a problem with the cover pass. (And I assume the root)


Straps cut for the bend, but again it was a failure because of the root.




And the reason for the fail.

So I had decided not to bother updating this until I progressed because there wouldn't really be anything new to cover. I had been having trouble still laying that root down, and with the amount of time it takes to prep these to actually bend them, I really didn't want to bend one until I could feel good about it's chances of success. While other students have bent several they were failing usually because of the root pass having slag inclusions and when bent would rip wide open.

There are two bends. The face bend and the root bend. To move on to vertical up you have to pass a 2g bend.

So to give you an idea about the amount of time it takes to make one all the way to the bend I'll run down the time I spent tonight.

Last Thursday I got one done and cut it once to see if I would make the other 3 cuts. I showed it to my teacher as I do all of them, and he said I could cut the rest out and try it but I knew he had serious doubts about it passing. So instead of wasting my time on that, I went out and bought some 1/8 Lincoln Excalibur (I ran out Thursday of the 3/32 10LB can) and a 5lb box of Radnor (Guy at Airgas told me its made by Lincoln and my class had apparently bought all the Excalibur out) and came into it fresh and determined that tonight was gonna be my night.

I started around 6pm tacking the pieces together and cranked it up to about 141 and started burning that root in and went nice and slow, made good fusion and made some great restart which I am always nervous about in a root. Second pass I kept it hot, burned that root further in and started laying my beads in. I got to the cover pass, and I do that with 3/32 (its our choice on what to use) and laid down good looking stringers, nice and uniform with no undercut and then I let it cool off some. I had all that done by 6:30ish and started the process for cutting them, and this took around and hour because I had to show another guy in my class how to run the band saw and then had to tack a plate on two pieces to secure it in the saw. By the time I got down with all that, doing like 6 cuts because the bandsaw is a bitch and didn't want to securely hold my coupon and having to wait for it to open up. So now it's a little after 8, and I start cutting the backing plates off and of course the hand band saw had a super dull blade so it took a while to get those done. Then I had to wait for the grinder to open up, and ground off the high spot where the coupon was and then I use the flapper disk to polish it up and make sure it's flat. Then I welded on two tabs on each one, and it had to be 100% cool before I could bend it. So I left it outside and started making another one because I did not have much faith I was gonna pass on my first bend. Now it's about 9:10 and I finally got to bend it. I gave it to my teacher and went to clean up my booth.

I was pretty nervous about it not passing, and decided I wasn't going to hover around and watch my work rip apart so I just finished cleaning up, and saw my teacher washing it off, and throwing some polisher on it and I realized if it had ripped he wouldn't be doing that so I went over to take a look. He said it passed, the root was fuzed perfectly and besides one very tiny line that he said was a stress fracture (I'm pretty sure its a scratch from my wire brush as I had welded the straps on after polishing it and I used my wire wheel to clean it back off) but it was structurally sound.

So while I made probably 7-9 of these in 2G, I only bent one. And it bent like a democratic politician on my first try. Pretty stoked on that.

Again my phone is pretty much useless and taking pictures is a bit of a hassle so I only got a couple. Unfortunately none of the cover pass but I did take a couple of the bends.

This is to show what the strap looks like before doing the grinding and polishing (the left strap is one I made a few weeks ago)



So these are the straps after being cut and polished


The straps with coupons added to the sides



And the bend. The scratches are from the wire wheel, not a defect like a fracture (I'll highlight what he said was a fracture so you can see it and decide for yourself)
