Generally, a spot welding machine uses two electrodes to squeeze the workpiece during operation, 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 electrode, an instantaneous thermal fusion is formed at the two contact resistance points, and a flow to the electrode is formed along the two workpieces to ensure that the internal structure of the workpiece to be welded is not damaged
