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. The term brazing is used when the temperature exceeds some arbitrary value, typically 880°F (470°C.)*

Gasbarre specializes in the design and manufacture of custom-engineered brazing furnaces specific to the thermal processing industry.
