If you need to disconnect two things that have been welded together, do you use an arc welder?

You can; you essentially weld too slowly and melt the work area, and let gravity or an air jet remove the molten metal. Or you can use a carbon rod in place of the wire feed and heat the metal up without adding new material. Both of these are kind of rough cutting techniques, though. If you had a plasma cutter around, you'd probably use it instead.

You could use a gas welder. It's not the *right* tool, but it'll work. (I was assuming that the futuristic hi-tech welder we were using was more like a gas welder than an arc welder.)

I'd be skeptical that an arc welder could work, but nathanw sounds more confident than I am so I'll believe him.

The key phrases to find information about the technique are things like "carbon arc cutting" and "air carbon arc cutting". Again, it's not a great technique, but it works in a pinch.

Weld, unweld...
Flying through space....

Look, I do the best I can. Personally, I'm _not_ a welder. I've never been one. If figured if you heat it up, you can probably stick something in there to pry it apart or somesuch. People are really clever.

And it took you a while to do, also.

I'm not complaining. I have a reasonable idea how 20th century welders work; I have no idea how umpty-umpth century welders will. You said it would do the job; that's all I needed.

I should point out that this post was not very relevant to the run last night, except it was inspired by it.

Is this not what Semtex is for?

Not to go on a tangent, but I think you need a secant person to cosine your liability waiver if you do.

Yeah, that's how I thought he meant it, too. :)
I am amused.

Likewise! Surprising, I'm sure. ;-)

That depends on what sort of condition you want them to be in after separation.

If the items in question are spot welded a firm blow with a sledgehammer may suffice.
