FIELD: nickel-base alloys.
SUBSTANCE: invention relates to nickel-base alloys as an additive agents in welded constructions as "noodles" or as welding wear. Nickel-base additive agent for welding high-strength nickel-containing alloys comprises the following components, wt.-%: carbon, 0.02-0.05; chrome, 10-18; molybdenum, 4-6; cobalt, 10-18; niobium, 2-6; aluminum, 0.5-1.3; tungsten, 0.5-5; titanium, 0.3-1.0; zirconium, 0.5-1.0; magnesium, 0.02-0.04; lanthanum, 0.02-0.05, and nickel, the balance. Additive agent shows enhanced strength of welded joint at room and increased temperatures, heat resistance of welded joints. Also, working resource and safety of welded constructions of engine hot tract are enhanced.
EFFECT: improved and valuable properties of additive agent.
