NIKKO Nickel Alloy Welding Electrode NC-400 belongs to the MMA Electrodes for Nickel-based Alloys range. Confirm classification, base material, welding current and operating conditions before requesting a quotation.

CLASSIFICATION

AWS A5.11 ENiCu-7 | BS EN ISO 14172 E Ni 4060 | JIS Z 3224 DNiCu-7

PRODUCT DESCRIPTION

The chemically basic flux is extruded onto a fully alloyed core wire with respect to nickel and copper. The flux also contains titanium to refine the weld metal and manganese to supress hot cracking. The slag has a low viscosity but a fairly narrow solidification range.

WELDING FEATURES OF THE ELECTRODE

The electrode is suitable for use on DC+ only. The slag fluidity and solidification range ensures excellent positional welding while the use of titanium ensures weld metal refinement and freedom from porosity. Metal recovery is some 100% with respect to the weight of the core wire

APPLICATIONS AND MATERIALS TO BE WELDED

For welding nickel, copper alloys, cast or wrought, including on site pipework. Typical materials are : ASTM – ASME UNS N04400, N04405, N05500.
A4.94 M35-1 cast A494 M35 cast. Proprietary alloys include: Monel 400 – R405 – K500 (special metals) It may also be used to weld Ni-Cu alloys to nickel, cupro-nickel and these to stainless steels.

OTHER DATA

Electrodes that have become damp should be re-dried at 180^oC for 30 mins.
