The Influence of the Electrode Extension on the Welding-Technological Characteristics of Pulsed Arc Welding Using Cored Wire

The results of investigations of the pulsed arc welding with a cored wire with increased extension are presented. As shown, the formation of droplets varies with increasing the electrode extension. Due to the oscillography analysis, this phenomenon is reasoned from the features of the impulse control. A range of parameters is set, for which a stable impulse control of the process is ensured. The increased production capacity and high arc stability are combined in this range.
