Spot welding is a high-speed, economical connection method. It is suitable for the manufacture of sheet metal members which can be lapped, joints which do not require airtightness and have a thickness of less than 3 mm. It is to weld the weldment at the individual points on the contact surface of the joint. Spot welding requires metal to have good plasticity.

Spot welding is usually divided into two categories: double-sided spot welding and single-sided spot welding. In double-sided spot welding, the electrodes are fed from the sides of the workpiece to the weld. A typical double-sided spot welding method is the most common method, in which case there are electrode indentations on both sides of the workpiece.
