S-NCI is a graphite type coated electrode, depositing nickel weld metal. Hardening of heat affected
zone is small and machining of the welds is comparatively easy. Therefore it is suitable for welding
alloy cast iron of poor weldability, malleable cast iron and hydraulically pressured parts as well as
common cast iron.
Chip off base metal completely at the repairing part.
There is a possibility that cracks spreads or makes holes at both ends of repairing part.
Keep the weld metal length less than 50mm(2 inch) to disperse welding heat. Adopt back
stepping stone or symmetry method by turns.
Hot peen in every pass.
The preheat temperatures vary in accordance with the size, kind and shape of base metal. 150
(302 ) is appropriate in general.
