A complex of investigations was performed to study the technological capabilities for application of combined gas-slag protection in MIG-process of copper alloy deposition on steel. It is shown that at semi-submerged arc surfacing (by semi-open arc) it is possible to control the technological characteristics of the welding arc, namely: increase its spatial stability, improve the pattern of electrode metal transfer (essentially reducing its spattering fraction), as well as ensure high-quality protection of the deposits from oxidation. Application of such a combined protection is particularly rational at highly efficient process of two-electrode MIG surfacing. 7 Ref., 1 Tabl., 7 Fig.
Keywords: copper alloys, combined gas-slag protection, spatial stability of the arc, two-electrode surfacing, deposited metal quality
