    The following are seven common welding equipment and equipment classification and composition:

    (1) hand arc welding equipment. Manual arc welding equipment is simple, simple and flexible, adaptable, but high requirements for welder operation. Manual arc welding is suitable for welding of metal materials such as carbon steel, low alloy steel, stainless steel, copper and copper alloy.

    (2) submerged arc welding equipment. The submerged arc welding equipment is composed of welding power source, submerged arc welding machine [1] and auxiliary equipment. Its power supply can be AC, DC or AC and DC. Submerged arc welding machine is divided into two categories: automatic welding machine and semi automatic welding machine. (1) semi-automatic submerged arc welding machine. (2) automatic submerged arc welding machine.

    (3) semi automatic CO2 gas shielded arc welding equipment for CO2 gas shielded arc welding equipment is mainly composed of welding power supply, gas supply system, wire feeding mechanism and welding torch.

    (4) inert gas shielded arc welding equipment, manual inert gas welding equipment, including welding torch, welding power and control device, gas supply and water supply system four parts.

    (5) the plasma arc welding equipment of plasma arc welding equipment mainly includes welding power source, control system, welding torch, gas path system and waterway system.

    (6) ultrasonic welding equipment ultrasonic welding equipment mainly includes ultrasonic plastic welding machine and ultrasonic metal welding machine.

    (7) the cold welding machine is based on the principle of high frequency spark discharge, which has no thermal surfacing on the workpiece. Cold welder can deposit, seal, and repair the defects of metal workpiece, such as wear, scratch, pinhole, crack, defect deformation, hardness reduction, trachoma, damage and other defects. The operation is simple, low heat input, no heat input in the instant process of surfacing, so the die is not deformed, annealed, bite and residual stress, and does not change the metal structure of the mold or product. The precision of the repair is high, the thickness of the coating is from a few microns to a few millimeters, so it only needs to be polished and polished. Also can carry on the vehicle, milling, planing, grinding and other mechanical processing, as well as electroplating and other processing.
