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.
