Background

Welding: also known as welding, meltallizing, is a process and technique for joining metals or other thermoplastic materials, such as plastics, by heat, heat or pressure. 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 joining the workpieces after the molten pool is cooled and solidified, wherein a melt filler can be added for assistance when necessary. (2) Pressure welding, namely the process of welding, pressure must be applied to a welding piece, and the method belongs to the processing of various metal materials and partial metal materials. (3) And brazing, namely, adopting a metal material with a melting point lower than that of the base metal as brazing filler metal, wetting the base metal by using the liquid brazing filler metal, filling a joint gap, and mutually diffusing the liquid brazing filler metal and the base metal to realize the link weldment. It is suitable for welding various materials, and also suitable for welding different metals or different materials.
