This article proposes a technology for producing fused welding fluxes using plasma granulation. The developed technology enables producing welding flux granules with carbide-containing additives. This is possible due to high dynamic and temperature effects of plasma arc on mineral raw materials that stops refractory additives from melting and thus remaining in welding materials composition. Using petrographic analysis, it was found that silicon carbide particles remain unchanged in granules of fused welding fluxes composition. Plasma granulation technology makes it possible to obtain both finished products such as welding fluxes and a charge ready for manufacturing cored wire and coated electrodes.
