I've been trained in TIG welding and bicycle frame building. I would
not recommend this approach! Any TIG welder who will work for "a slab of beer" isn't to be trusted around bicycles. Tolerances are tight, bicycle tubing is relatively thin and it is
extremely easy to have it distort (or burn through) unless you know exactly what you're doing. Tweak the alignment even a bit during welding and the bike will never ride straight again. Do the repair
right or don't do it at all...
