In spot welding, two workpieces to be welded are first clamped by the upper and lower electrodes under the action of a welding clamp or welding gun cylinder.

For low-carbon steel sheets with a thickness of 1-1.5 mm, the maintenance time is 0.1-0.2 seconds, while for welding low-carbon steel with a thickness of 8-10 mm, the full crystallization of the welding nucleus requires around 1.5-2.5 seconds. Therefore, the maintenance time should not be less than this value.
