NIHONWELD NC-112
AWS Specification: ENi-Cl
JIS Specification:

DFC Ni

Other Specification:

Non-conductive coating

I. APPLICATIONS:

Hot and cold welding of gray cast iron.  The electrode is recommended for the welding of areas of difficult access.  Joining and surfacing of machines, frames and housing of gray cast iron, bearing blocks,etc.

     II. DESCRIPTION:

A pure nickel electrode with non-conductive coating.  Ignition does not occur upon contact between coating and workpiece. The electrode melts rather slowly and consequently the wetting on the base material is very good.  The deposit is mechanically machinable.

     III. NOTES ON USAGE:

 

  • Clean base metal before welding.

  • If there is a possibility that cracking spreads, make the stopholes at both ends of repairing part.

  • Keep bead length less than 50 mm to disperse welding heat.  Adopt back step, stepping stone or symmetry method by turns.

  • Hot peen in every pass.

  • It is not necessary preheating and postheating in general but satisfactory results can be obtained by preheating at 100-200ºC in accordance with kind, shape and size of base metal.

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.
