The resistance welding process of automobile sheet metal parts usually includes the following steps: 1. **Preparation work**: Select an appropriate resistance welding machine and adjust welding parameters such as welding current, welding time, and electrode pressure according to the material and thickness of the sheet metal part. At the same time, ensure that the surface…
DetailsAdvantages of resistance welding: **I. High welding efficiency** 1. Fast welding speed: Since resistance welding uses the resistance heat generated when current passes through the weldment to achieve welding, it heats up quickly and the welding time is short. Usually, the welding of a weld spot can be completed within a few seconds, so the…
DetailsResistance welding is a method that uses the resistance heat generated by the current passing through the weldment and the contact area as the heat source to locally heat the weldment and apply pressure at the same time for welding. Its principle is to heat the weldment to a molten or plastic state through the…
