brazing

When the melting point of the flux is low, it is called soldering, such as soldering; when the melting point of the flux is high, it is called brazing, such as brazing; when the flux is not melted, it is called diffusion welding when it is connected by heating diffusion. Brazing refers to the use of a filler metal (called solder or solder) whose melting point is lower than the melting point of the base material (brazed material). At a temperature lower than the melting point of the base material and higher than the melting point of the solder, the liquid solder is used. A welding method in which the surface of the base material is wetted, spread, and filled in the gap between the base materials, and the base material is dissolved and diffused, and the joint between the parts is realized. When the melting point of the flux is low, it is called soldering, such as soldering; when the melting point of the flux is high, it is called brazing, such as brazing; when the flux is not melted, it is called diffusion welding when it is connected by heating diffusion.
