Description

technical field [0001] The invention relates to the field of welding technology, in particular to an intelligent brazing device and a brazing method. Background technique [0002] Brazing is essentially a special kind of brazing, which relies on the molten solder or the liquid phase formed by the diffusion between the surface of the base metal and the solder, spreads the base metal under capillary action, and interacts. Coating preparation means. The prepared coating has the advantages of high bonding strength, small thermal stress, smooth surface and high precision. Traditional brazing methods such as induction brazing and furnace brazing require a lot of manual operations. At the same time, during the coating preparation process, there is a lack of monitoring of coating morphology and temperature field, and the quality of the obtained coating needs to be improved. Therefore, the research and development of intelligent brazing equipment, especially the real-time monitorin...
