Based on the analysis of the forces acting on the drop of a liquid metal of an electrode during mechanized welding, this article shows that gravity and electrodynamic forces can be used to accelerate the drop detachment from the tip of electrode. This provides a transition to the transfer of micron scale liquid metal droplets. According to the results of analysis, the perspective direction of the electrode metal transfer management during the process of mechanized welding with modulated current is determined. The results of experimental studies are presented. They confirm the possibility and suitability of the facing by self-protecting powder wire with its intermittent feed and the obtainment of a high-quality layer of weld metal as well as the decrease of the temperature influence on a base metal.

Key words: mechanized welding and facing, electrode metal, electrode metal transfer, electric arc processes.
