I think part of the issue with tig brazing for framebuilding is that you cant sink enough heat into the part to build the size of fillet needed for a structural braze on a frame. could be done with multiple passes maybe? Gotta watch out as well, dont tig braze with gas welding rod,AFAIK the zinc content vaporizes then you end up with some unpleasant ailment if you huff too much... even with mask.
I think its viable to do bridges and brazons with tig tho, that dont require that big a fillet
I believe this is all correct. Another reason not to use it for fillet or lug brazing frames is that it won't wet through as well as gas brazing rod, meaning the joint it relatively weak on the inside.
