AWS Specification: ENi-Cl
JIS Specification:

DFC Ni

Other Specification:

PHIL MARKET ONLY

I. APPLICATIONS:

For low heat welding of cast iron parts such as machines housings, frames, for building up worn part and correcting machine cuts and casting flaws. Best suited for nodular cast iron and joining steel to cast iron and also for welding difficult to weld cast iron.

II. DESCRIPTION:

high strength electrode with machinable deposit for cast iron welding.  The deposit is crackproof.

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 50mm 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.
