Abstract :
The arc is the technological tool in the arc welding process. Improved welding quality requires precise control of the arc in all different welding phases. This paper presents some possibilities of arc control for the gas-metal-arc welding process, by using the conventional electrical parameter range and an extended electrical parameter range achieved by an auxiliary power electronic circuit. Another way is to use an external magnetic field for controlling the arc
