Characteristics:
LKE-Ni-CI is a covered electrode with graphite type coating and pure Ni alloy core rod. The weld metal provides excellent machining property, good tensile strength and good crack resistance
Applications:
It is suitable for the repair welding of high pressure parts and cast iron products, etc
Notes on Usage:
1.Hot peening to prevent the shrinkage stress.
2.Clean up to prevent the contamination.
3.Preheat is not needed.
4.Use small amperage and keep the arc as short as possible
