Description

technical field [0001] The invention relates to the technical field of induction brazing, in particular to a vacuum induction brazing device and a method of use thereof, which are mainly used for welding products with high quality requirements and easily oxidizable materials. Background technique [0002] Induction brazing is realized by using the resistance heat of the induced current in the weldment. The induction heating method is different from other heating methods. The heat is not transferred to the workpiece by the environment or the medium, but the high frequency or power frequency electric energy is transferred by the induction coil. Input to the metal workpiece, the turbine heat induced in the workpiece is a self-heating process to melt and spread the solder. Induction brazing has the advantages of concentrated energy transmission, extremely fast heating, and local brazing. However, the disadvantage of induction brazing is that brazing is generally carried out in ...

AI Technical Summary

Problems solved by technology

However, the disadvantage of induction brazing is that it is generally brazed in an atmospheric environment, and the weldment has a tendency to oxidize. Generally, it is necessary to use flux to remove the film to achieve the brazing process.

However, the heat transfer mode of vacuum brazing belongs to radiation heat transfer, and the heat transfer efficiency is low, so the heating time of vacuum brazing is long and the brazing efficiency is low
