FIELD: manufacture and restoration of articles of copper-nickel alloys containing 8 - 18% of nickel including articles operating in sea water (fish protecting apparatuses, pumps and so on).
SUBSTANCE: welding wire contains next relation of ingredients, mass %: nickel, 9.0 - 20.0; iron, 0.6 - 1.5; manganese, 0.8 - 1.5; titanium, 0.2 - 0.4; silicon, 0.08 - 0.15; copper, the balance. Total quantity of reducing agents (Mn + Ti + Si) is to be no less than 1.15 mass %. Nickel content in welding wire exceeds its content in welded alloy at least by 1 %.
EFFECT: improved manufacturing properties of wire, possibility for producing corrosion-resistant welded joints with dense metal of seam having no cracking, pores and other flaws.
