Abstract

PURPOSE: To ensure desired quality of weld zone by detecting the resistance between electrodes during welding process, and controlling the welding pressure between the electrodes so that the resistance coincides with the resistance of preset reference resistance curve.
CONSTITUTION: In resistance welding, the resistance between electrodes that hold the material to be welded inbetween is detected when welding current is being applied. The resistance is compared with the resistance of preset reference resistance curve every moment or at predetermined specific time. The resistance between electrode is changed to coincide with the resistance of the reference resistance curve by controlling welding pressure in accordance with the difference between the values of resistance.
