Abstract
Results of investigation of the effect of fluxes on the process of argon-arc tungsten-electrode welding are considered. Special attention is given to analysis of factors that cause increase in operational characteristics of the arc and, in particular, increase in the penetration depth. It is assumed that increase in the penetration depth is caused by growth of the Lorentz force due to contraction of the arc by flux and increase in current density in the anode region. The effect exerted by changes in the gradient of surface tension of molten metal in the weld pool on penetration is of a secondary importance.
Keywords: arc welding, tungsten electrode, argon, arc plasma, current density, penetration depth, flux, dissociation
