Brazing Furnaces

Furnace brazing is a semi-automated process used to join metal components with a dissimilar, lower melting filler metal. It allows designs of one or multi-joint assemblies to be joined by a reproducible metallurgical bond.

Brazing Furnaces were first commercialized in the early 1920s. Furnace-brazed parts are heated to a specific brazing temperature until the filler metal flows. The parts are then cooled or “quenched,” usually in a different zone of the furnace, or in a separate chamber, to produce the required material properties in the finished assembly.

Brazing Furnace’s capabilities and advantages include:

• Multiple joints on the same assembly can be brazed simultaneously
• Gravity or minimal fixturing is sufficient making complicated jigging typically unnecessary
• Undesirable atmosphere constituents can be controlled or eliminated
• Multiple atmospheres or chambers make various types of processing operations possible
• The process is highly repeatable, ideally lending itself to automated production
• Brazing furnaces usually do not require chemical fluxes
• Little to no post-braze cleaning is required
• Provides close temperature control, for optimum and uniform results

Abbott Furnace Company custom designs and manufactures continuous belt brazing furnaces in both straight or humpback designs.  These furnaces are used in the manufacturing process where there is a need to join simple or complex designs of one joint or multi-joint assemblies.

Abbott Furnace Company’s continuous belt brazing furnaces ensure consistent brazing results by offering superior temperature and atmosphere control.
