Brazing
Brazing is a welding method that uses liquid brazing material to fill the gap between solid workpieces and heat the brazing material and the workpiece to the melting point of the brazing material.Brazing has small deformation and smooth and beautiful joints, and is suitable for welding precise, complex components made of different materials, such as honeycomb structure plates, turbine blades, carbide tools and printed circuit boards. Before brazing, the workpiece must be carefully processed and strictly cleaned to remove oil stains and excessively thick oxide films to ensure the interface assembly clearance.
Compared with fusion welding, the base material does not melt during brazing, only the brazing filler metal melts; compared with pressure welding, no pressure is applied to the welded parts during brazing. The weld formed by brazing is called a brazing seam. The filler metal used for brazing is called a brazing filler metal.
