Abstract

The paper presents outcomes of comprehensive research that examines the relevance of protective surface coatings on a product to be welded for such parameters as MMA welding stability, width of temperature fields on the surface of a welded structure, as well as structure and phase composition of the deposited metal. The experimental study has associated the use of a protective coating in MMA with an increase in certain characteristics - shortcut period of arc gap (5-11 %); bridging time (10-12 %); mass of transferred electrode metal droplets (up to 50 %); amplitude value of the welding current (25 %); size of a deposited metal grain; and a heat affected zone (15-25%).
