Heating characteristics of DN1S CNC stainless steel spot welding machine-Xinxing Welding Machine

1. The influence of resistance on spot welding heating 1) Contact resistance between the electrode and the workpiece: heat generation 5~10% Function: The heat generated by the contact resistance plays an important role in establishing the temperature field in the early stage of welding and the uniform flow of the welding current 2) Internal resistance of the workpiece itself: 90~95% heat generation Function: this part
