WELDING WIRE FOR WELDING DIFFERENT STEELS Russian patent published in 2016 - IPC B23K35/30 C22C38/58 

FIELD: metal processing.

SUBSTANCE: invention relates to welding, particularly to composition of welding wire for welding different steels, used at high temperatures and sign-variable loads, including in aggressive media, particularly in conditions of operation of equipment of nuclear power engineering. Welding wire for welding different steels contains carbon, silicon, manganese, chromium, nickel, nitrogen, sulphur, phosphorus, molybdenum, zirconium, cerium and iron at following ratio of components, wt%: carbon 0.021-0.033, silicon 0.40-0.60, manganese 2.10-2.50, chrome 23.50-24.50, nickel 12.50-13.50, nitrogen 0.07-0.09, sulphur - not over 0.01, phosphorus not more than 0.015, molybdenum 0.30-0.80, zirconium 0.05-0.08, cerium 0.05-0.08, iron - balance, wherein total amount of carbon, sulphur and phosphorus is not more than 0.05 wt%.

EFFECT: technical result is increased resistance of weld metal to formation of hot cracks and high strength and plasticity of weld joint.
