Can be used in electronics, electrical appliances, aviation, aerospace, machinery manufacturing, home appliance manufacturing, eyeglass frames manufacturing, refrigeration, medical products manufacturing, ...... and so on, it's very extensive.
High-frequency brazing is the use of high-frequency electronic equipment for induction heating of metal parts.
Relying on the workpiece in the alternating magnetic field of alternating current to generate induction current resistance heat to heat the brazing method. Since the heat is generated by the workpiece itself, it is heated rapidly, the oxidation of the surface of the workpiece is less than that of brazing in a furnace, and it prevents the development of grain growth and recrystallization of the parent material, and it can also be welded in a vacuum or protective gas.
In addition, localized heating of the workpiece can be achieved.
Brazing is the use of lower than the melting point of the base material of the metal material as brazing material, the weldment and brazing material heated to higher than the melting point of the brazing material, lower than the melting temperature of the base material, the use of liquid brazing material to wet the base material, filling the gap between the joints and diffusion of each other with the base material to achieve the connection of the weldment method. Brazing deformation is small, smooth and beautiful joints, suitable for welding precision, complex and composed of different materials components, such as honeycomb structure plate, turbine blades, carbide tools and printed circuit boards. Before brazing the workpiece must be carefully processed and strictly cleaned to remove oil and excessive thick oxide film, to ensure that the interface assembly gap. The gap is generally required between 0.01 ~ 0.1 mm.
