The color of the deposit has a high resemblance to cast iron, therefore is particularly suitable for the elimination of casting defects on
new parts. Hardness about 165 HBOK. Deposition is done on
cold or slightly preheated material. The weld metal is well machinable. Castings containing phosphorus
levels higher than normal (approximately 0.20%
phosphorus) are more readily welded using these electrodes
than with an electrode of the ENi-CI classification. Experience
has shown that satisfactory welds can be made on
thick and highly restrained weldments, and on high strength
and engineering grades of cast iron.
Electrodes with special basic-graphite coating and alloy core nickel and copper.

Materials to be welded
Used for normal grades of cast iron such as gray-, ductile- and malleable irons and for joining work pieces of various types of cast iron,
including nodular iron, and for welding them to steel and some nonferrous base metals.
