NIHONWELD NC-100N
AWS Specification: ENi-Cl
JIS Specification:

DFC Ni

Other Specification:

DIN ENi G4

I. APPLICATIONS:

Used for repair and build up of cast iron part as auto blocks and heads, cylinder walls, motor exhaust parts, impeller rings, valve seats, cast iron dies, defective castings, correcting machinings errors, joining steel to cast iron etc.

     II. DESCRIPTION:

counterpart of NC-100 with higher strength and harden weld deposit due to additions of Mn and Fe.

     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.
