WELDING WIRE FOR WELDING STRUCTURAL PARTS FROM DIVERSE STEELS Russian patent published in 2012 - IPC B23K35/30 C22C19/05 

FIELD: process engineering.

SUBSTANCE: invention relates to welding and may be used for welding diverse structures made of low-alloyed steel and cleft welding in nuclear power engineering. Proposed welding wire comprises the following components in wt %: carbon - not over 0.03, silicon - not over 0.5, manganese - 1.0-2.0, chromium - 18-20, molybdenum - 14-16, iron - not over 0.5, sulfur - not over 0.01, phosphorus - not over 0.015, vanadium - not over 0.1, tungsten - not over 0.01, titanium - not over 0.15, aluminium - not over 0.2, nickel making the rest. Carbon content vs total content of molybdenum and vanadium - 6.6-6.9, while sulfur content vs total content of titanium and manganese - 0.018-0.019.

EFFECT: optimum physical-mechanical properties, resistance to intergranular corrosion, ruling out martensitic structure in weld seam metal.
