The purpose of the work is to develop and improve technologies for manufacturing high-quality welded joints in order to increase the productivity of processes, improve the quality and ensure high performance indicators of welded and welded products. Research methods – computational and software data processing tools, experimental research. Improvement of the technological process of applying a coating with the use of a pulsating spray flow, which leads to a significant reduction in the burnout of alloying elements, leads to an increase in the strength of the adhesion of particles to each other during layer-by-layer application on the surface. The use of a pulsating spray flow during electric arc spraying contributes to an increase in the amount and level of productivity and efficiency of the use of the sprayed material due to the reduction of the oxidizing effect of the spray flow and the rational use of arc energy. Reducing the formation of non-metallic inclusions in the weld is interesting to study the influence of carbon additives, because the gaseous CO oxide and carbon dioxide CO2 formed with the participation of carbon are easily removed and do not contaminate the weld metal with non-metallic inclusions.
