General characteristics
ERCuNi consumables are used for the welding of wrought or cast 70/30, 80/20, and 90/10 copper-nickel alloys to themselves or to each other and for surfacing applications where high resistance to corrosion, erosion, or cavitation is required.
Preheating generally is not necessary. . The arc should be kept as short as possible to assure adequate shielding gas coverage and thus minimize porosity. Suitable for corrosion resistant surfaces and coatings, as long as a 400 alloy or pure Nickel substrate is made. Applications include offshore construction, desalination plant, evaporators, condenser, in salt and sea water processing system.
