An Advanced Gas Metal Arc Welding Machine Design for Low Spatter Welding

Abstract

In the short-circuiting metal transfer in gas metal arc welding (GMAW), melted metal explosions occur when the arc is re-ignited after the short circuiting. This can result in spatter on and around the welding beam, and the spatter requires extra cleaning work after welding. Many investigations and patents have been made to reduce the spatter in GMAW by fast regulation of the output current. The main objective of this paper is to experimentally demonstrate the effectiveness of the fast regulation of the output voltage and output current with the proposed hybrid control method in the GMAW application
