Principle of Battery Spot Welder:
The battery spot welder uses the resistance heat generated by the current passing through the weldment and the contact area as the heat source to partially heat the weldment, and at the same time applies pressure to the weldment for welding. During the welding process, a nugget will be formed at the contact between the electrode and the weldment, thereby realizing the connection of metals.
