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.

Electroslag welding flux

The invention provides a coated electrode for producing a nickel-base weld deposit containing at least 12 weight percent chromium. The coated electrode includes a flux surrounding the core wire. The flux includes in parts by weight 5 to 35 strontium carbonate, 5 to 35 total metal carbonate compound, 0 to 20 manganese with at least 5 manganese present when less than 0.5 weight percent manganese is present in the core wire, 10 to 40 fluoride compound and 5 to 45 oxide compound. A binder is used to hold the flux to the core wire.
