What are the welding equipment?

There are the following types of welding equipment: 1. Cold welding machine.

Cold welding machine uses the principle of high-frequency electric spark discharge to carry out athermal surfacing on the workpiece. Cold welding machine can deposit, seal and repair the wear, scratches, pinholes, cracks, defects, deformation, hardness reduction, trachoma and damage of metal workpieces. The welding positioner has the advantages of simple operation, low heat input, no heat input in the instant process of surfacing, no deformation, no annealing, no undercut, no residual stress, no change in the metal structure state of the mold or product, and high repair accuracy. The thickness of the coating varies from several microns to several millimeters, and it only needs grinding and polishing. Machining such as turning, milling, planing and grinding, and post-treatment such as electroplating can also be carried out. Hand arc welding equipment

Manual arc welding has simple equipment, simple and flexible method and strong adaptability, but it requires high welder operation. Manual arc welding is suitable for welding metal materials such as carbon steel, low alloy steel, stainless steel, copper and copper alloy. 3. Submerged arc welding equipment

Submerged arc welding equipment consists of welding power supply, submerged arc welding machine and auxiliary equipment. Its power supply can be AC, DC or both. Submerged arc welding machine is divided into automatic welding machine and semi-automatic welding machine. 4. CO2 gas shielded welding equipment

Semi-automatic CO2 gas shielded welding equipment is mainly composed of welding power supply, gas supply system, wire feeder and welding torch. 5. Inert gas shielded welding equipment

Manual inert gas shielded welding equipment includes welding gun, welding power supply and control device, gas supply and water supply system. 6. Plasma arc welding equipment

Plasma arc welding equipment mainly includes welding power supply, control system, welding torch, gas path system and water path system. 7. Ultrasonic welding equipment

Ultrasonic welding equipment mainly includes ultrasonic plastic welding machine and ultrasonic metal welding machine.
