Welding in many ways, the characteristics of the welding process can be divided into: Welding Alloys, pressure welding and brazing three categories
1 Fusion welding
Welding process, weldment joints heated to a molten state, without the pressure to complete the welding method is called welding. Depending on the different heat sources, such welding welding, welding, electroslag welding, gas welding, electronic beam welding and other ways.
2 bonding
Must butt welding process, to exert pressure (heated or not heated), bonding to the completion of the welding method is called, belong to this type of welding method of resistance welding (spot welding, seam welding, butt welding, etc.), friction welding , ultrasonic welding, cold welding, and other.
(3) brazing
Brazing is lower than the melting point of the base metal of the metal material for brazing, weldment and filler metal is heated to above the melting point of brazing, lower than the melting point of the base metal, liquid solder wetting the parent metal to fill the joint gap brazing, soldering, and base metal interdiffusion connect weldment belong to thisTypes Of Welding Wiremethod.
