I. APPLICATIONS:

N-NiCu-7 is a very popular electrode. Most common uses include electroplating and chemical pickling equipment, polyvinylchloride production plants, sea water desalination plants and in waste water treatment plants.

     II. DESCRIPTION:

N-NiCu-7 flux-coated electrodes are designed for shielded metal arc welding of nickel-copper Monel® 400 and 404 to themselves and to steel. This electrode is perfect for joining many nickel-copper alloys to copper, copper-nickel, carbon steel and low alloy steel. NIHONWELD N-NiCu-7 is also used for overlaying on steel and for welding the clad side of joints in steel clad with a nickel-copper alloy.

     III. NOTES ON USAGE:

  • Its weldability is as same as austenitic stainless steels.

  • Keep the interlayer temperature under 100ºC and cool it as fast as possible.

  • Keep the welding current as low as possible.

  • Dry the electrodes at 150 ~ 200ºC for 30 ~ 60 minutes before use.

TEST RESULT

The information contained or otherwise referenced herein is presented only as “typical” without guarantee or warranty, and Industrial Welding Corporation expressly disclaims any liability incurred from any reliance thereon. Typical data and Test results for mechanical properties, deposit or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards, and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
