2. Pressure welding, in which pressure must be applied to a welding piece in a welding process, belongs to the processing of various metal materials and partial metal materials.
3. Brazing, namely, a metal material with a melting point lower than that of the base metal is used as brazing filler metal, the liquid brazing filler metal is used for wetting the base metal, a joint gap is filled, and the liquid brazing filler metal and the base metal are mutually diffused to realize a link weldment.
Tin alloys are low temperature alloying metals, lead-free tin alloys have a melting point tm such as Sn99Ag0.3Cu0.7 at 217. (T224' C. generally, the texture of the tin powder material begins to change when the ambient temperature to which the metal is exposed reaches a temperature of 0.3TM, which is the tempering temperature of the metal material, which in a typical tin alloy is about 6 (TC; when the ambient temperature to which the metal is exposed reaches a temperature of 0.7TM, the metal powder begins to sinter.
