In daily steel production, the application of intermediate frequency spot welding machines has been increasing. Do you know how to maintain intermediate frequency spot welding machines in daily life? Now let the editor of Dongguan Chuangde Laser Intelligent Technology explain to you how to maintain the intermediate frequency spot welding machine in daily life.
Firstly, the surface of the workpiece welded by the intermediate frequency spot welding machine should be kept clean. Due to the fact that the contact area of the electrode in a medium frequency 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 have a significant impact on the formation of fusion nuclei. As the electrode tip deforms and wears, the contact area increases and the strength of the solder joint decreases. 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 excessive current density, can result in splashing and surface burning. Therefore, thoroughly cleaning the surface of the workpiece is a necessary condition to ensure that the intermediate frequency spot welding machine obtains high-quality joints.
Mid frequency spot welding machine is a resistance welding method that involves assembling and connecting welded parts, pressing them between two electrodes, and using resistance heat to melt the base metal to form solder joints. Mid frequency spot welding machines are commonly used for connecting thin plates, such as aircraft skins, chimneys for aircraft engines, and car cab shells. The intermediate frequency spot welding machine welding transformer is a spot welding electrical device, and its secondary only has one loop circuit. The upper and lower electrodes and electrode arms are used for both conducting welding current and transmitting 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 the electrodes in a medium frequency spot welding machine directly affects the welding process, welding quality, and productivity. Electrode materials are commonly made of copper, cadmium bronze, chromium bronze, etc; There are various shapes of electrodes, mainly determined by the shape of the welded component. When installing the electrodes of a medium frequency spot welding machine, it is important to ensure that the surfaces of the upper and lower electrodes are parallel; The electrode plane of the intermediate frequency spot welding machine should be kept clean and often trimmed with sandpaper or file.
