What is AWS Class ENiCu-7 Coated Electrodes?

The ENiCu-7 Coated Electrodes are primarily made up of nickel (about 65%) and copper (30%), with small amounts of iron, manganese, and other elements added to boost strength and corrosion resistance. They excel in resisting seawater, salts, and reducing acids. Welds created with these electrodes typically reach tensile strengths of 70–85 ksi and demonstrate good ductility and toughness. The unique coating guarantees a stable arc, effortless slag removal, and minimal porosity, even when welding under less-than-ideal conditions or with contaminated base metals.
