WELDING FLUX WITH INCREASED BASICITY

摘要

FIELD: welding process. SUBSTANCE: welding flux comprises, %: SiO2, 30-34; MnO, 30-34; MgO 26-28; CaF3, 5-7; CaO, up to 5; Al2O3, up to 1.5; Fe2O3, up to 1.5; S, up to 0.2; P, up to 0.2. EFFECT: improved technological characteristics of flux and decreased its hydroscopicity while chemical composition of weld metal is retained. 1 tble
