Welding flux is a granulated powder with a grain size from 0.2 to 4 mm, designed for welding processes. In the process of welding, the granules melt and emit gas, and then during cooling they form a crust of slag.
Welding fluxes are classified by production technology, chemical composition, purpose, and other characteristics.
Our company produces fused welding fluxes produced by the method of double refining of the melt and the use of mineral waste welding production. A new method of cooking fluxes allowed to improve the welding and technological properties of fluxes, reduce the need for natural raw materials, and also solve the environmental problem.
