Abstract
The theoretical model developed to describe contraction of the arc by flux allows for the processes occurring at the anode, variations in thermal conductivity of the arc gas and phenomena taking place on the arc column periphery, and establishes their analytical relationship with size of the conducting arc plasma column and the anode spot. Distribution of current density in the anode spot determined by analytical calculations using the said model is close to that determined by experimental measurements.
Keywords: welding over the flux layer, arc, tungsten electrode, anode, plasma, thermal conductivity, negative ions, current density
