Principle of vacuum brazing furnace
There are two types of brazing furnace, vacuum and non vacuum. Here we mainly explain the vacuum brazing furnace. Understanding its principle will also help us to understand its use methods and precautions.
Vacuum furnace brazing is of high quality and expensive equipment. The conventional process is to apply flux to the parts to be cleaned and decontaminated, spread solder (powder, granular and flake) and put another part to be welded (the welding surface is also coated with flux). After positioning and fixing the two parts, put them into the furnace and heat them up to the temperature of solder melting to complete the welding. It uses the furnace temperature to raise the temperature of the workpiece, and melts the solder whose melting temperature is lower than the workpiece, so that the workpiece can be welded. Among them, the choice of solder is very important, this process has high yield, good quality and small deformation. Suitable for mass production.
