I've always associated oxyacetylene torch with the brutish but necessary industrial activity of welding but never art. Well, the resulting metal thingy may be an artistic sculpture, but the acts of cutting and welding themselves be art?
Here's a video clip by benderautomatic over at SuicideBots blog that's aiming to prove that metalwork itself is a kinetic art: http://www.suicidebots.com/2010/09/10/oh-yeah-baby-drag-that-tip/ [embedded YouTube]
I make sculptures out of metal, and definitly feel welding and torch cutting are an art. Sure, most anyone could weld or cut, but it takes a fine touch to do both properly. If sparks and slag are flying all over the place, you need more practice.
