How to Make a Metal Ring Using an Oxygen-Acetylene Welding Torch
The Voice: Hey, Kevin. What were you doing?
Kevin Caron: I'm making a metal ring for this new sound sculpture that I'm working on here in the studio. This is one of the rings that will go on the top of the bell, and then fit into the stand.
This is a piece of a coil spring out of an old pickup truck that I had lying around for years, and I've just been using little snippets of it every now and again for various contemporary art commissions.
You have to get the hardness out of the spring that they build in when they make a spring out of it, so you can twist it, move it and warp it while welding.
I've been using the rosebud (that's the name of that tip right there). It puts out lots of flame, lots of heat. It allows you to heat up thick metal really quickly, rather than spending a lot of time with a smaller torch tip trying to heat it up, or having to fire up the forge just to work on two little pieces.
Now I need to weld this together, then we'll fire the rosebud up again and heat it up all the way around, a little bit at a time.
You can see the metal is not quite flat. It's got a little ripple in it, so I'll have to heat it up, take it over to the anvil and work it on the anvil to flatten it out, straighten it and get it smooth and round the way I want it.
That's what we're doing.
