Abstract
The invention provides an electroslag welding flux that is especially useful for welding copper-nickel alloys. The electroslag flux contains by weight percent 50 to 95 fluoride compound, 0 to 45 oxide compound, 1 to 25 rare earth-containing material, 1 to 45 potassium-containing material and 0 to 25 metallic. Advantageously, the flux contains by weight percent 60 to 90 fluoride compound, 5 to 40 oxide compound, 2 to 20 rare earth material, 1 to 20 metallic, 2 to 35 potassium-containing material, 0 to 15 carbonate and 0 to 35 binder. Most advantageously, the flux contains by weight percent 65 to 90 fluoride compound, 5 to 35 oxide compound, 2 to 15 rare earth-containing material, 1 to 15 metallic, 3 to 35 potassium-containing material, 0 to 5 carbonate and 1 to 35 binder.
