Abstract
The paper presents the results of evaluation of influence of a combined shielding on gas saturation of metal at the stage of a drop and a pool in welding and surfacing of copper and its alloys. Parameters of the process of submerged arc welding and surfacing using an additional gas shielding were optimized. A new method of a pulsed supply of shielding gas into the arc zone in submerged arc welding and surfacing was developed.
