Background
Spot welding is a welding method in which a welding spot is formed between the contact surfaces of two overlapped workpieces by using a columnar electrode during welding. During spot welding, the workpiece is pressed to be in close contact with the workpiece, then current is switched on, the contact position of the workpiece is melted under the action of resistance heat, and a welding spot is formed after cooling. The workpiece joint needs to be placed between an upper electrode and a lower electrode of the spot welding machine and clamped during spot welding, namely, the two parts are required to have complete binding surfaces during spot welding, and the upper electrode and the lower electrode of the spot welding machine are respectively positioned on two sides of the binding surface of the workpiece to be welded.
