Application and Characteristics of Copper and Aluminum Butt Welding Machine

The copper wire butt welding machine uses the two ends of the electrode to press the two ports of the butt-welded parts respectively. After the power is turned on, the upsetting cylinder will gradually advance the two broken ports at a set speed. The current density of the first contact part of the port in the process of approaching Very large, it will instantly liquefy to form metal lintels and blasting to produce metal splashes, that is, flashing; as the ports gradually approach, the number of connection points gradually increases, and finally the entire end surface is formed with countless liquid metal lintels, which are continuously blasted to make the end surface After being heated to the critical point of plasticity and liquidity, a large upsetting force is applied to the two ends immediately and the pressure is maintained for a period of time, and the two ends are welded together to form a stable joint.

The copper wire butt welding machine is mainly used for the butt joint of the end faces of the parts. Generally, the butt joints must have the same shape and cross-section. They can be used for plates, round bars, square bars, pipe fittings, and profiles. The materials that can be joined include ordinary carbon steel, stainless steel, aluminum, and yellow. Butt joint between copper, red copper and dissimilar metals.

Copper wire butt welding machines can be divided into handle type, gas-liquid hybrid type, servo motor type, and hydraulic type according to the different flash kinetic energy structure.

The copper and aluminum butt welding machine adopts PLC and programmable program controller to control each welding program of the welding machine.

It can realize the optimized control of the entire welding process of preheating, flashing and upsetting, and at the same time make the operation process more convenient; it has reliable welding performance and effectively guarantees the welding accuracy of the workpiece. This series of butt welding machines are widely used for butt welding of cross-sections between carbon steel, alloy steel, and non-ferrous metal tubes, rods, plates, and profiles.

The welding machine is equipped with a high-precision hydraulic regulating valve in the hydraulic system, which can adjust the hydraulic flow rate flowing in a unit of time, thereby effectively ensuring the accuracy and consistency of the flashing speed during welding, and ensuring the flashing process. It is stable, so that the slag inclusion at the welding joint of the welding workpiece is greatly reduced, and the deformation of the internal diameter phase structure is reduced. At the same time, the quality of the welding part of the workpiece is reliable, firm and beautiful.

When the welding machine is a semi-automatic working process, the auxiliary time of the whole welding process is short, the labor intensity of the workers is reduced, and the production efficiency is greatly improved.
