ABSTRACT:
A predetermined value is used for adjusting welding power to an optimum value to consistently achieve sturdy welds. The predetermined value is not affected by variations in workpiece materials and in wear of electrodes. Preferably, total power per unit volume of the workpieces is used as the predetermined value. In a resistance welding system, total power per unit volume required to satisfactorily weld the workpieces is calculated from a total thickness of the workpieces and a welding time. From this calculated total power per unit volume, power per unit volume and per unit time is calculated. The present welding system adjusts one of the welding current or the welding voltage to an optimum value required to produce the predetermined value.
