Skills of Spot Welding of Different Thickness Plate by Energy Storage Spot Welding Machine

About the skills of spot welding of plates with different thicknesses by energy storage spot welding machines, I believe many friends are interested. Today, Sester Technology will introduce to you.

There are many places where we usually use the energy storage spot welding machine. For example, nut bump welding is a common welding process. Then the question arises. How does our energy storage spot welding machine spot weld products with different thicknesses or materials? Today, Xiao Bian will answer this question for everyone to facilitate users of the energy storage welding machine to better use the energy storage spot welding machine.

Energy storage spot welding machine Welding skills for plates with different thicknesses:

1. Use electrodes with different contact surface diameters or spherical radii to adopt smaller diameter or spherical radius on the side of thin parts or workpieces with good electrical and thermal conductivity, to increase the current density on this side, and to reduce the effect of heat dissipation from the electrodes on thin or conductive pieces.

2. The side of the workpiece with good thermal conductivity is made of copper alloy with poor thermal conductivity to reduce the heat loss on this side. The workpiece gasket is used to pad a gasket made of metal with poor thermal conductivity on the side of the thin piece or the workpiece with good thermal conductivity to reduce the heat dissipation on this side.

3. Due to the short power-on time, the influence of contact resistance heat generation between workpieces is increased, and the influence of electrode heat dissipation is reduced, which is conducive to overcoming core offset. This method has obvious effect in spot welding of extremely thin parts and thick parts. Sester capacitor energy storage welding machine, like Sester intermediate frequency inverter DC spot welding machine, can spot weld workpieces with relatively large thickness. For specific equipment selection, you can consult Sester technicians and we will give you the best advice.
