The article proposes the technology for producing fused welding fluxes grains of various structures, fractional and chemical composition using a highly concentrated heat source. Interaction processes between the highly concentrated heat sources and mineral raw materials are presented in the article. The necessary components for obtaining welding flux with various granule structures are determined. The proposed technology allows to obtain welding flux granules with a range from 0.1 to 3.0 mm that meets regulatory documentation requirements. It was found that during the process of plasma granulation there is a decrease in the concentration of alkali metals to the required content for welding fluxes. At the same time, there is an increase in the concentration of basic elements such as silicon, calcium, aluminum and other metals
