Spot welding machine welding spot displacement sometimes, how to solve?

spot welding machine welding spot sometimes offset, so how to solve the displacement of the welding spot? I believe many friends are interested, the following science and technology Xiaobian to introduce to you.

spot welding machine adopts strong standard welding, that is, high current and short time, which increases the heat generation of contact resistance between workpieces and reduces the heat dissipation of electrodes. Capacitor energy storage welding machine, medium frequency spot welding machine with high current and short power-on time can be welded to a large thickness ratio of the workpiece is an obvious example.

1. Use electrodes with different surface diameters, and use smaller diameters on the side of thin parts or workpieces with good electrical and thermal conductivity to increase the current density on this side and reduce the impact of electrode heat dissipation.

2. Different electrode materials are used, and copper alloys with poor thermal conductivity are used on the side of thin parts or workpieces with good thermal conductivity to reduce heat loss on this side.

3. Use process gasket: Pad a gasket made of metal with poor thermal conductivity on the side of thin parts or workpieces with good electrical and thermal conductivity to reduce heat dissipation on this side.
