Description

[0002] The spot welding machine adopts the principle of double-sided double-point overcurrent welding. When working, the two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode to the other, 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 this electrode to form a loop, and will not damage the internal structure of the workpiece being welded.

[0003] However, the existing automatic spot welding machines can automatically perform spot welding actions at a certain frequency, but this process still requires the operator to manually move and adjust the position of the welded product.
