Furnace brazing is a mass production process for joining the components of small assemblies with a metallurgical bond, using a nonferrous filler metal as the bonding material and a furnace as the heat source. This article presents the advantages and limitations of the furnace brazing and reviews three types of furnaces: continuous, semi-continuous, and batch. It presents three examples of the industrial applications of the furnace brazing: vacuum devices, jet engines, and automotive industries. The health and safety guidelines to be followed during the furnace brazing are also discussed.
