BHCP4 Furnace Brazing

Furnace brazing (FB) is a brazing process in which assembled components with preplaced brazing filler metal are joined together in a furnace. The furnace is purged with a gaseous atmosphere or evacuated of air to provide a specified low partial pressure of air. It is then heated to a temperature above the liquidus of the brazing filler metal but below the melting point of the base metals. The resulting brazements are then cooled or quenched using appropriate methods to minimize distortion and produce the required properties in the filler and base materials. This cycle is designed to produce the required melting and solidification of the brazing filler metal to join the components without melting or damaging the base metals.
