Been a while since I welded anything (and never titanium). But Titanium requires a shielding gas. Titanium reacts with oxygen like crazy. So much so that when in liquid form (pretty much what your weld will be) it can actually remove oxygen from hydrogen in water (which is all around us). That creates hydrogen gas which is not good because hydrogen is sluttier than a fat chick at last call and will react with anything.

I think you are suppose to use helium for Ti which is also super expensive becuase it requires a lot (He is much lighter than air). Because you use a non-reactive noble gas you won't get the discoloration taht oxygen causes.

Why wouldn't you use argon?

Yep, that's what the guy in this thread did. He mentioned it a few pages into the linked thread.

Argon would work. I just thought I remember some Ti welders I knew mentioning they like to use helium for Ti. Helium is not reactive at all while Argon can be slightly more reactive due to a larger electron cloud. As in it is easier for other elements to pull away an electron from Argon which has a larger electron cloud (where electrons are farther away from the nucleus) than it is from helium which has a much smaller one.

But from a macro level such as welding a Ti frame I doubt it matters much.

That's pretty fucking hot. Needs to do something about that tail light and I've seen trick billet timing belt covers that would looke fucking money on that...

i;ve been thinking about the belt covers myself, i i like open covers dunno if a person actually rides teh bike if you want open covers, exposed to the elements and rocks and such vs a "show" bike no biggie.

I don't think I'd be too worried about rocks and shit...
