silver soldering stainless is the only way I know to join it
other than heli-arc .... it works okay, in my experience -- though
that's limited and there are probably alloys that it doesn't work
well with ... dunno.  My problem is that it seems it would ablate
away until a leak occured -- esp in a bend in the direct path
of the exhaust flow             ???
