ABSTRACT:
An electrode displacement monitoring and control system for predicting and adaptively controlling resistance weld quality. The distance (34) between the movable electrode (16) and a fixed point such as on a workpiece (12) surface is monitored during a resistance weld cycle. The displacement information is processed and applied as a control signal for dynamically and adaptively varying various weld parameters including current application in order to control weld quality. A reversal in the direction of electrode displacement is identified and used in the adaptive control strategy.
