[0002] Existing battery spot welding machines basically use the principle of double-point overcurrent welding to spot weld batteries, that is, the workpiece is pressurized through two electrodes so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes. At this time, when the welding current flows from one electrode through the other electrode, an instantaneous thermal weld is formed at the two contact resistance points, and the welding current instantly flows from the other electrode along the two workpieces to the electrode to form a loop, completing the battery spot welding.
