welding
Welding, also known as welding or welding, welding, is a way to join the metal or other thermoplastic materials such as plastic manufacturing process and technology. The weld is achieved by the following three ways: ▪ The workpiece to be joined is heated to form a molten bath. The molten bath is cooled and solidified and joined, if necessary, by adding a melt. Melting the workpiece itself, by welding the capillary effect of the workpiece (such as soft welding, brazing) ▪ in the equivalent of or below the melting point of the workpiece by the high pressure, laminated extrusion or vibration so that the two pieces of mutual penetration between the joints (Such as forging, solid welding) according to the specific welding process, welding can be subdivided into gas welding, resistance welding, arc welding, induction welding and laser welding and other special welding. ...
