I registered for about 20 credits of electives this quarter with the idea of dropping whichever seemed the least useful. Thing is, that seems to be the welding night class that I've taken a liking to. Its going to have the least outside homework, for sure, and its gonna be a lot easier on my health than CNC machining at 8am.
Anyway, which of these three classes should I pass up;
I'm guessing welding is the least useful, since.I would always take night classes somewhere else, but Id like to hear what actual professional s have to say about it.
Depends what you want to do, really.
Welding is technically one of the more useful things. If you know how to weld anything to anything using anything, you have a shitton of options for when you want to cobble something together or even just straight up get a job with decent pay. If you like it, that's a bonus.
There's a bit of shit you need to learn by heart in welding when you get in there properly, don't put off the reading material. Just me personally, I hated welding and I was also terrible at it. Can't weld to save my life after a year of college doing welding. I'd rather just machine a whole thing out of bar stock than weld two little things together.
CNC machining/manual machining is what I do for a living and in terms of "usefulness", what I learned in class was actually useful for the shit I do every day. Manual machining experience is probably the most useful to get a "feel" for shit; someone that's never seen a tool cut steel and goes straight into CNC machining often gets expensive very fast. A manual machinist that doesn't know a G-code is tends to be somewhat less useful when required to make edits to a program or even prove one out/do shit on a CNC. Keep in mind that you'll probably be working on light Bridgeport mills (low horsepower, machines that weigh maybe 2000lbs at most) while most full-on CNCs have about ten times the power and rigidity. There are plenty of super heavyweight, unstoppable strong manual machines but you probably won't be dealing with those.
Fluid power databook, and take shit slow around hot oil. 2000PSI of black gold will fuck you up and you won't even know it.
As for how useful a class in that stuff could be, I don't really know. I had a class in hydraulics, gearing, air systems, belts, and rudimentary shop electronic circuitry. Just a primer on stuff really, enough to show us what a "danger, do not touch" sign was like for each system.
Again, what do you want to be?
