Abraferro NiFe2
Ferro nickel electrode graphite-basic coated
Description & applications
Graphite basic coated electrode with a Ferro-Nickel alloy deposit for joining and repairing nodular cast iron. Sound deposit, highly resistant against cracks. Particularly recommended for dissimilar welding of cast iron to steels and constructions of cast iron. Good hooking and flow of the weld metal.
Main applications: Repairing of defects in foundries, repairing of engine blocks, houses of tool machines, gearboxes, reducing parts, pump bodies, cast pieces, valve bodies.
Grey cast iron, malleable and nodular cast iron:

Welding Instructions
Weld on clean and exempt from grease surfaces (previous grinding of the joint).Reduce the heat input to a minimum, weld with the lowest practical amperage, keep temperature low ( < 100°C) in order to reduce the risk of cracks in the base metal, depose short beads of about 6 cm and peen immediately. Reignite on the weld metal and not on the casting
