Abstract

This paper describes recent developments at the University of Wollongong in the application of novel control strategies to improve the control of inherently unstable transfer in the GMAW process. The paper reviews the problems involved in maintaining arc stability with CO2 shielded arcs and proposes potential solutions based on the development of a new process control technique. Results of early investigations into the phenomena are reported.
