The research and description of modern methods and procedure of welding flux manufacture are presented. The technology of welding fused flux production by influencing on the composition of mineral raw materials furnace burden (from 0,5 mic up to 0,20 mm) with electric arc (diameter graphite electrodes 6-18 mm, current from 200 up to 600 A) is proposed to be significantly reducing the labor input as well as dustiness during the operation and transport and improves mechanical properties (granules strength of 16-19 N/mm2) and surface condition of flux granules. The equipment for the granulation does not require large melting furnace and powerful transformers, fuel gas, coke or oil, i.e. welding flux is easy to manufacture.
