Brazing is the use of a metal with a lower melting point than the base material as the brazing filler metal. After heating, the brazing filler metal melts, but the weldment does not melt. The liquid brazing filler metal is used to wet the base metal, fill the joint gap and diffuse with the base metal to make the weldment firm. Connected together.
According to the melting point of the solder, brazing is divided into soft soldering and brazing.
