Abraferro
Ferro nickel electrode
Description & applications
Graphite basic coated electrode with a Ferro-Nickel alloy deposit for joining and repairing nodular cast iron. Deposit homogeneous and highly resistant against cracks. Particularly recommended for dissimilar welding of cast iron to steels and cast iron constructions.
Good bonding and flow of the weld metal.
Main application
: Welding 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 the 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.
