Abstract

Weld penetration control is one of the most difficulty problems in welding area. In this study, a simple method using arc voltage to derive the weld penetration is employed in pulsed gas metal arc welding (GMAW-P). And a predictive controller is designed to control the system output, the change in arc voltage during peak current period. Some welding experiments are conducted to validate the controller. Experiment results show that the change in arc voltage during peak current period can be controlled to a certain constant by the predictive controller.
