Monel Alloy 400 Welding Electrode

As a leading supplier of nickel alloys, we manufacture Monel 400 (ENiCu-7) welding electrodes in different sizes. The nominal composition (wt %) of weld metal produced by electrodes of this classification is 66 Ni, 30 Cu, 3 Mn, and 1 Fe. Electrodes of this classification are used for welding nickel-copper alloys to themselves and to steel, for welding the clad side of joints in steel clad with a nickel-copper alloy, and for surfacing steel with nickel-copper alloy weld metal.

Electrodes through the 1/8 in [3.2 mm] size can be used for welding in all positions. Electrodes larger than that are used only in the flat and horizontal positions. The weld metal is suitable for service both in the as-welded condition and after an appropriate postweld heat treatment. Qualification tests should be conducted beforehand to make certain the necessary properties can be obtained after the particular heat treatment is employed.
