Weld-L's

just had the dual exhaust system in my Bronco re-done -- they
used a torch and rod (had a MIG rig, but didn't use it) ... the
guy said it was basically brazing rod

so ..... has anyone tried brazing or silver soldering ???  I'd
think the brazing would hold up quite well but would suspect the
silver solder -- esp if in a bend on the outer curve where it
gets the direct blast from the exhaust.  The advantage of the silver
solder is you can work with stainless (don't need heli-arc)
