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 especially when the shielding gas is the carbon dioxide. 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. This fast output regulation can reduce 50 % to 80 % amount of spatter, which highly increases the productivity and reduces the cleaning work. 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. Both bandwidth of the voltage and current control loop are about 4 kHz.
