I have a copper boiler design going, and have contemplated TIG welding it.
Steamchick and I had a lengthy discussion about this.
As I recall, you don't need a special copper for welding boilers, but check me on that.
I did not buy special copper.
And it would seem that you need a lot of amperage to weld copper.
It seems one way to circumvent needing a high amperage TIG machine is to preheat the copper in a kiln.
I have seen several TIG welded copper boilers online, and it seems to be a successful and fully accepted method, if done correctly.
One would have to be well versed with TIG welding.
