ENiCu-7 electrode is used to weld nickel-copper alloy to itself and to steel, to weld the composite side of the joint in nickel-copper alloy composite steel, and to surfacing the steel with nickel-copper alloy weld metal.
Electrodes smaller than 1/8 inch（3.2 mm） can be used for welding in all positions. Electrodes larger than this size are only used in flat and horizontal positions. Weld metal is suitable for use in a welded state and after proper post-weld heat treatment. Qualification tests should be carried out beforehand to ensure that the necessary properties can be obtained after the application of a particular heat treatment.
- ENiCu-7 is a flux coated electrode designed for welding of nickel-copper Monel 400 and 404 to themselves and to steel
- Perfect for joining many nickel-copper alloys to copper, nickel-copper, carbon steel, and low alloy steel
- Used for overlaying on steel and for welding the clad side of joints in steel clad with a nickel-copper alloy
Although the chemical composition of ENiCu-7 is very close to that of regular Monel 400, there are still significant differences between them. Please be sure to confirm with the supplier before placing the order.
