Background

Welding is a manufacturing process and technique for joining metals or other thermoplastic materials, such as plastics, by applying heat, pressure, or both. Welding accomplishes the purpose of joining by three ways: 1. fusion welding, namely heating the workpieces to be jointed to locally melt the workpieces to form a molten pool, and jointing the workpieces after the molten pool is cooled and solidified, wherein a melt filler can be added for assistance when necessary, so that the welding process is suitable for welding various metals and alloys without pressure; 2. pressure welding-a welding method in which pressure, heat or no heat must be applied to a workpiece during welding. The method mainly comprises the methods of resistance welding, friction welding, explosion welding and the like, has the characteristics of high production efficiency and good welding quality, and can be used for welding some special metals; 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.
