IDENTIFICATION
Gricast N, ENiCI
CLASSIFICATION
AWS/SFA5.15: ENiCl, IS: 5511-1991: ENi
DESCRIPTION
An extruded & graphite type coated electrode depositing pure Nickel weld metal for cold welding of cast Iron. Weld able in all positions. Arc striking and re-striking properties are excellent. Arc is soft & stable. The weld metal including the heat effected zone is easily machinable.

TYPICAL APPLICATIONS
Joining and surfacing of all types of Cast Iron, without pre-heating of the parent metal Repairing of mechanite, alloy & malleable cast iron.
WELDING INSTRUCTIONS
• Chip off the base completely at the repairing part.
• If there is a possibility that cracking spreads, make the stop holes at both the ends of repairing part.
• Keep the weld metal length less than 50mm to disperse welding heat. Adopt back stepping stone or symmetry method by turns.
• Hot peen in every pass.
• The preheat temperature vary in accordance with size, kind & shape of base metal. 150°C (320°F) appropriate in general
