Mold brazing
Shenzhen Su's heat treatment mold vacuum brazing
Vacuum brazing is an advanced process for joining parts in a vacuum atmosphere without using flux. One of the biggest features is the protective effect of vacuum. In addition, vacuum can also degas the base metal and remove oxides on the surface of the workpiece. It can realize those materials and structures that are difficult to connect by ordinary methods, and obtain smooth and dense brazed joints with excellent mechanical properties and corrosion resistance. At present, this kind of process has become an indispensable production method in cutting-edge industries such as aviation, aerospace, atomic energy, and electrical instrumentation, and has been promoted and popularized in petroleum, chemical industry, automobiles, tools and other related machinery manufacturing fields.
In order to ensure sufficient welding penetration, reasonable alloying reaction, avoid welding defects, and obtain good welding joints. Welding process parameters should be selected reasonably. The process parameters of vacuum brazing include: vacuum degree, heating speed, brazing temperature, holding time, cooling method, furnace temperature, etc. Among them, the most important process parameters are brazing temperature and holding time, which directly affect the filler joint filling and the interaction between the filler metal and the base metal, thereby determining the quality of the joint.
