    Resistance welding process is one of the most common welding processes for low-voltage electrical contact component products. The welding quality of contact components directly determines the performance of low-voltage electrical switch products. In the welding process of low-voltage electrical contact components, reasonable selection of metal electrode materials and their structural design are necessary conditions to ensure the stability of the product's resistance welding process and obtain the best welding quality of the product. For some contact component products made of special materials to be welded, the corresponding welding process must be designed according to the characteristics of the contact and bracket materials, so as to ensure the welding quality and meet the good performance of the contact components.

    In the resistance welding process of low-voltage electrical contact components, the electrode material selection principles are: ① Select electrode materials with low conductivity on the side of the workpiece to be welded with high conductivity; ② Select electrode materials on the side of the workpiece to be welded with low conductivity Electrode material with high conductivity.

    Through reasonable electrode material selection and shape design, weld nuggets with symmetrical depth distribution should be formed as much as possible on both sides of the workpiece to be welded to achieve the ideal welding effect. In addition, while referring to the basic principles of electrode selection, we must also consider some special circumstances of the actual production of the product. Sometimes the ratio or shape of the upper and lower electrodes for manual welding and automated welding of the same product will be different, so the selection of welding electrodes must be Good welding quality can be obtained by considering many factors such as welding efficiency, welding process and convenience of actual operation, and setting reasonable welding parameters.
