"Welding" refers to joining parts with a filler that is the same, or
similar to the parent metal. "Brazing" refers to joining parts with a
lower melting point filler. In many situations, brazing is actually
stronger than welding. For stainless, welding requires an inert shielding
gas, such as helium (heli-arc), argon, or CO2 (TIG or MIG), none of which
are possible with a torch.
