NONE

Other Specification:

I. APPLICATIONS:

Typical applications N-Ni-1 would involve the chemical industry, soda, fabrication, fatty acid fabrication, vinyl chloride production, sodium metal silicate production and within the paper industry. N-Ni-1 should be considered where high resistance to corrosion and high temperature is required.

     II. DESCRIPTION:

N-Ni-1 is a high nickel content flux-coated electrode designed for welding wrought and cast forms of commercially pure nickel to themselves or to steel. This electrode is commonly used for dissimilar welding applications involving nickel base alloys 200 or 201 to iron base and nickel base alloys. N-Ni-1 is excellent for overlaying on steel and for welding the clad side of nickel clad steel.

     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.
