Pneumatic energy storage spot welding machine uses low-power grid energy, stores it in capacitors, and discharges the welded work instantly through a resistance welding transformer in a short period of time to generate a large pulse current for welding. Energy storage spot welding machines are mainly suitable for welding stainless steel, aluminum, copper, and some non-ferrous metals.
Maintenance of Pneumatic Energy Storage Spot Welding Machine
Due to the fact that the contact area of the electrode in a pneumatic energy storage spot welding machine determines the current density, the electrical resistivity and thermal conductivity of the electrode material are related to the generation and dissipation of heat. Therefore, the shape and material of the electrode in a pneumatic energy storage spot welding machine have a significant impact on the formation of fusion nuclei. With the deformation and wear of the electrode end of the pneumatic energy storage spot welding machine, the contact area increases and the weld strength will decrease.
The oxides, dirt, oil, and other impurities on the surface of the workpiece increase the contact resistance. Excessive oxide can even prevent current from passing through. Local conduction, due to the high current density of the pneumatic energy storage spot welding machine, can cause splashing and surface burning. Therefore, thoroughly cleaning the surface of the workpiece is a necessary condition to ensure that the pneumatic energy storage spot welding machine obtains high-quality joints.
The spot welding of pneumatic energy storage spot welding machine is a resistance welding method in which the welded joint is assembled and pressed between two electrodes, and the base metal is melted by resistance heat to form a welding point.
Pneumatic energy storage spot welding machine welding transformer is a spot welding electrical device, and its secondary circuit only has one loop. The upper and lower electrodes and electrode arms of the pneumatic energy storage spot welding machine are used to conduct welding current and transmit power. The cooling water circuit passes through parts such as transformers and electrodes to prevent heating. When welding, the cooling water should be supplied first, and then the power switch should be turned on. The quality of electrodes in pneumatic energy storage spot welding machines directly affects the welding process, welding quality, and productivity.
The electrode materials for pneumatic energy storage spot welding machines are commonly made of copper, chromium zirconium copper, etc; There are various shapes of electrodes, mainly determined by the shape of the welded component. When installing the electrodes of a pneumatic energy storage spot welding machine, it is important to ensure that the surfaces of the upper and lower electrodes are parallel; The electrode surface should be kept clean and often trimmed with sandpaper or file.
