Brazing

Nowadays, one of the most commonly used forms of furnace brazing is the process carried out in a vacuum furnace, commonly called vacuum brazing. The parts to be joined are usually cleaned and held in place with an interlayer of brazing material applied to the joining surfaces, and then placed on a fixture inside the furnace. The entire assembly of brazed parts is brought to the melting temperature of the brazing material, while air is removed from the furnace to eliminate any oxidation or contamination that may occur as the brazing material melts and fills the gap between the joined components. For very complex assemblies, furnace brazing successfully replaces the welding operation. It also allows for the combination of brazing and hardening treatments in a single cycle.
