Welding! Welding is a glorious, mystery-infused, thoroughly bad-ass way to stick things together. Welders move in their own cloud of mythos and danger – they are dirtier, tougher, and sexier than other kinds of makers, and the things they build are big and strong and hold our world together. This positive stereotype permeates at all levels of pop culture: if a character is introduced while welding, you immediately know that they will be some kind of blue-collar superhero, or some kind of cliched contradiction – the welder quoting Hegel after winning the bar fight, or the classic trope of seeing a welder at work, and then, they flip off their helmet, and OMG IT’S A GIRL! A GIRL WELDING!
Over on Make: Projects, I’ve written a welding tutorial to get you started with barely any gear at all – simply three car batteries and some jumper cables give you the ability to perform basic stick (arc) welding.

Who doesn’t want to get in on this skill set? Soldering makes electronic magic happen, knitting keeps you warm, but knowing how to weld will make attractive people of whatever orientation you are into swoon. Everyone wants to know how to weld. The biggest problem, for most people, is that you need access to a welding machine.
There are a few options here: you can borrow someone’s welding rig. I suppose welders are common on farms, but only 2% of Americans live on farms, and if you are one of them, you were probably out welding the cows and milking the corn within minutes of birth (I have only a vague idea of what goes on at farms, as you can see. Something with dirt, right?) If you live in the grittier, more industrial parts of cities, there are welding shops all over the place, but they are dark, scary places (part of their appeal) and if you were to walk into one, expecting to find dedicated tradesman open to the DIY spirit and eager to teach a snot-nosed kid, you will quickly discover that welders are dark, scary, busy people, bribe-able with beer, maybe, but not usually interested, at all, in teaching.
You can buy a welder. You can pick up a cheap 110v stick welder for about a hundred bucks (check big hardware stores, Amazon, or Craigslist) or a bare-bones, break-in-a-couple-of-hours MIG (wire feed) machine for under $150 (just saw some for that much, and lower, on Amazon. Do not buy them. They are garbage), but I know that many, many people cannot even afford that.
Also, if you are not sure about the whole welding thing and want to try it out, or just need to do a day of welding to finish that one big project, or need to repair things every now and then, buying a new piece of equipment is probably not the best course of action, especially since when it comes to welders (as it is with pretty much everything else), you get what you pay for.
The final option, and best for the poor or non-committed-to-welding maker, is to build a welder. There are many ways to do this, ranging from impressive feats of DIY electrical engineering all the way down to the easiest, simplest one: wiring together some car batteries. It is quick and uses stuff you either have lying around or can pretty easily obtain. Follow the instructions, and you can go from zero to welding in under an hour.
Caveats, cautions, and all that
Welding is dangerous! Even if you take every possible safety precaution, you will occasionally burn and cut yourself, and electric shocks and retinal burns are very common, even if you know what you’re doing — and you probably do not. Skimp on safety and you can blind yourself, suffer injuries that will make hardened ER doctors puke, and die in any number of closed-casket ways. When you’re starting out, wear a good, rated helmet, thick gloves, non-flammable natural fiber clothing (as much leather as possible), and boots. Later, when you have a couple of hundred hours of welding experience and the scar tissue has rendered you insensitive to pain (and pleasure — a downside of welding), you can do the weld in a T-shirt or gloveless bit, but at that point, you will know what you’re getting into (and trust me — UV-burned armpits suck).
One important bit of information that other welding tutorials leave out: At first, you will be horrible at this. There is a good chance you will not even be able to strike an arc, or if you do, you will not be able to maintain one. Or, if you can maintain one, you will burn through the things you are trying to weld or not really weld them at all. People tend to not document their failures online, and it is easy for the person who’s new at welding (or skateboarding, or juggling, or pretty much anything) to forget that the thing they are trying to learn is hard, and that the flaw is not in the instructor, but in the student. The flaw is in the student, but not in the way that you might think — remember that worthwhile things are hard and people do not document their learning curve or all of their countless failures. You will fail, but just keep trying and you will eventually get it right. It will just likely take longer than you think.
Lastly, welding is really not the be-all/end-all panacea for fabrication. It is difficult to do on anything except for steel, welded things are hard to take apart, and the heat tends to distort small or thin parts.
With all that said
