[TheForge] welding red brass, slightly OT

[ries]

Tig brazing is much easier than gas brazing, in my book.
Its so much more controllable, and, functionally, it feels just like  
tig welding- you have to learn to work the rod in the puddle, by  
feeding it rather than just blasting it with the arc, but it is quite  
possible to build as big of a fillet as you want. And fill gaps with  
multiple passes.
Copper alloys suck up the amps though- pure copper is the worst, but  
my guess is that this stuff would also like a pretty powerful welder-  
200 amps, minimum.
Bring a sample over, we can try it out.

Ries, thanks for your thoughts on the Brass- it's from Alaskan, 23000 is
the designation, 85% cu 15% zinc
Brazing would be ideal- the architect sez he can't get radii in the size
he wants so all corners would be fabbed.
I've done a bunch of brazing on silver and all the plumbing in our house
is copper...fit up would be the big issue, I'm guessing.
New to TIG brazing- any pointers, relative to OA?
Never have gotten on top of filling gaps with brazing material, though I
do hear stories of it being done.
Thanks,
Andy
