FIELD: welding of high silicon austenite steels of equipment mounted inside reactor for operating at high temperature and in contact with lead-base melt metal heat transfer agents.
SUBSTANCE: welding wire contains next ingredients, mass %: carbon, 0.005 - 0.030; silicon, 1.60 - 2.40; manganese, 1.00 - 2.00; chrome, 15.00 - 17.00; nickel, 10.00 - 13.00; tungsten, 1.20 - 2.00; titanium, 0.20 - 0.60, zirconium, 0.06 - 0.18; iron, the balance. Relation of total content of titanium and zirconium to carbon content is to be no more than 22.
EFFECT: enhanced long-time and technological strength, lowered trend for heat embrittlement of seam metal.
