NIHONWELD N-NiCrCoMo-1
AWS Specification: ENiCrCoMo-1
JIS Specification:

NONE

Other Specification:

I. APPLICATIONS:

N-NiCrCoMo-1 is suitable for joining and surfacing high-temperature alloys. Special applications of the N-NiCrCoMo-1 are in oxydizing media at high temperatures, especially for the construction of gas turbines, combustion chambers and ethylene production plants.

     II. DESCRIPTION:

N-NiCrCoMo-1 can be welded in all positions except vertical-down. Smooth, stable arc, very good slag removal. The seam is finely rippled and notch-free.

     III. NOTES ON USAGE:

Hold electrode as vertically as possible, keep a short arc, only a very little weaving. Fill end crater carefully. Interpass temperature max. 150°C. Re-dry electrodes for 2-3hours/250-300°C.
