Description

technical field [0001] The invention relates to the field of brazing equipment, in particular to a brazing and detection device. Background technique [0002] Brazing is to use a metal material with a lower melting point than the base metal as the solder, heat the weldment and the solder to a temperature higher than the melting point of the solder and lower than the melting temperature of the base metal, use liquid solder to wet the base metal, fill the gap between the joints and The method of interdiffusion with the base metal to realize the connection of the weldment. Brazing is mainly used in the manufacture of precision instruments, electrical components, dissimilar metal components, and complex thin plate structures, such as sandwich components, honeycomb structures, etc., and is also commonly used for brazing various types of different wires and carbide tools. When brazing, after cleaning the contact surface of the workpiece to be brazed, it is assembled in the form o...

Problems solved by technology

[0003] With the development of science and technology, many new materials have emerged. As an important connection technology, brazing has unique flexibility and advantages for the connection of new materials and the manufacture of complex and fine structures. However, the traditional brazing method mainly uses Vacuum brazing consumes a lot of energy, the brazing time is long and the brazing process is uncontrollable, and it is impossible to perform dynamic analysis on the formation process of the welded joint and welding defects. Although vacuum brazing and transient liquid phase (TLP) diffusion welding are more advanced than traditional brazing The welding method has great advantages, but the vacuum brazing furnace is still used for welding, which cannot solve the problems of low welding efficiency and real-time monitoring of the evolution of the welding structure
