I've seen it done,but never done it myself. A
friend used to weld 10 mm I.D. titanium filling
tubes for a bleach bottle filler. When they were
damaged, he dropped them into a small open topped
tank which he consciously purged with argon before
and for a minute or two after tig welding them. He
used titanium filler rod,but I don't know where he
got it from. It was quite successful, and the
welds looked OK as well.

Bicycle shops (design ones anyway) do it all of
the time.
Search for them on the net - maybe some hints.

a shield gas.

The problem is, we've never worked with
titanium before. Can it be Tig
welded? Can we use stainless rod, or should we
get something else. Is the
argon OK?
