Welding technology, also known as joining engineering, is an important material processing technique. The definition of the weld is as follows: the process of forming a permanent bond by heating or pressing or both the materials of the workpieces to be welded (the same or different materials) with or without a filler material to achieve atomic bonding is called welding. The welding method is a welding method which utilizes a columnar electrode to form a welding spot between the contact surfaces of two overlapped workpieces 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 spot welding is mainly used for welding sheet component stamping parts with the thickness of less than 4mm, and is particularly suitable for welding automobile bodies, carriages and airplane fuselages.
