Stainless Steel Brazing Furnace - Gasbarre | Gasbarre

What is Brazing? Brazing joins metals by flowing a thin capillary thickness layer of non-ferrous filler metal into the space between them. Bonding results from the intimate contact produced by dissolution of a small amount of base metal into the molten filler metal, without fusion of the base metal.
