Cycling log: TIG welding

I was doing some research on how companies like Moots build Titanium-framed bicycles, and I had to check out this article from Wikipedia on TIG welding. Fascinating stuff. It makes me appreciate what Jesse James of West Coast Choppers once said about metal fabricators being artists as much as artisans. The skill level is incredible, and the danger is not inconsiderable if you don't know what you're doing.
