Selection of electrode materials for resistance welding equipment

About the electrode material selection of resistance welding equipment, I believe many friends are more interested, the following is a small series of science and technology to explain in detail. The electrode material, electrode shape and external dimensions of

resistance welding equipment enable the electrode to achieve good cooling, and the end surface of the truncated conical electrode head is regarded as a very good shape. The diameter of the end face is required to be 6~8mm, and grinding should be carried out in time if it exceeds 8mm, and the upper and lower electrodes of the welding tongs and the plate should be as vertical as possible during welding. When the external dimensions of the

electrode are expanded, due to the expansion of the contact area, the reduction of the current density and the improvement of the heat dissipation effect, the heating degree of the welding zone is weakened, so that the external dimensions of the nugget are reduced and the carrying capacity of the welding joint is reduced.

medium frequency inverter spot welding machine is one of the most advanced welding equipment, widely used, welding transformer small volume and large output energy. Because the frequency of the welding transformer is increased from 50/60HZ of the current mains to 1000HZ, it can greatly reduce the weight of the iron core material. In addition, the rectifier diode of the transformer secondary circuit changes the electric energy into DC current to provide welding machine application, which can greatly improve the induction coefficient value of the secondary circuit and save more than 30% of the user's power consumption.
