Beschreibung
Zusammenfassung:	FIELD: automatic fusion welding of low alloy steels with normal and increased strength including cold resistant steels. ^ SUBSTANCE: high impact work of seam metal is achieved by predetermined relation of basic and acidic oxides in flux and also by additional content of potassium and sodium oxides at next relation of ingredients, mass%: silicon dioxide, 21 - 27; calcium oxide, 11 - 17; magnesium oxide, 21 - 25; calcium fluoride, 14 - 20; aluminum oxide, 10 - 14; manganese oxide, 4 - 7; (potassium + sodium) oxides, 2 - 5; iron oxide, 1 - 3. Low- silicon low-manganese basic melted flux provides at welding by means of low alloy wire, seam metal with high factors of ductility and impact viscosity of low alloy cold resistant steels at temperature -40°C. ^ EFFECT: possibility for obtaining seam metal of high ductility and impact viscosity. ^ 1 tbl
