The welding principle of the cage welding machine

The cage welding machine adopts strong standard welding, that is, high current for a short time, so that the contact resistance between the workpiece increases heat production and reduces electrical heat dissipation. Capacitive energy storage welding machine, medium frequency cage welding machine using high current and short power-on time can weld the workpiece with a large thickness ratio is an obvious example.
1, the use of different outer diameter of electricity, in thin parts or conductive, good thermal conductivity of the workpiece side with a smaller diameter to increase the current density on this side, and reduce the impact of electrical heat dissipation.
2, the use of different electrical data, in thin parts or conductive, good thermal conductivity of the workpiece side with poor thermal conductivity of copper alloy, in order to reduce the heat loss on this side.
3, the use of process gaskets: in the thin or conductive, good thermal conductivity of the workpiece side pad a piece of metal made of poor thermal conductivity of the gasket to reduce the heat dissipation of this side.
