What are the main reasons for the wear and tear of the welding electrodes when using the capacitor discharge spot welder? There are three reasons as follows.
1. The choice of electrode material, according to the different welding products, the electrode material needs to be changed.
2. In the welding process, the effect of water cooling can effectively reduce the temperature rise and deformation of the electrode, thereby slowing down the wear and tear of the electrode, the welding process of the fusion area to the electrode to transfer a lot of heat.
3. Electrode electrode structure, the design of the electrode should increase the diameter of the electrode as much as possible, and reduce the extension length of the electrode while matching the workpiece, which can reduce the temperature rise caused by the heat caused by the resistance of the electrode itself.
