COMPOSITION OF WELDING WIRE Russian patent published in 2001 - IPC

FIELD: welding. SUBSTANCE: welding wire has the following components, wt. %: carbon, 0.04-0.12; chromium, 0.4-0.9; silicon, 0.2-0.5; manganese, 0.8-1.4; molybdenum, 0.2-0.6; vanadium, 0.1-0.4; sulfur, not more, 0.025; phosphorus, not more, 0.025; calcium, 0.05-0.12; nickel, 0.05-0.3; iron, the balance. In this case, ratio between carbon content and total content of molybdenum and vanadium shall be 0.12-0.13, and ratio of sulfur content to total content of calcium and manganese shall be within 0.016-0.029. EFFECT: higher efficiency and technological efficiency of articles welding from high-carbon steels due to higher resistance to hot cracks and fragile failure, viscosity in combination with higher anticorrosion hardness and strength of weld. 1 ex
