Elektrodai AV1 KetNiFeCu Ø4.0x350mm (1 kg)

Graphite-basic coating with a copper coated core wire and a Ferro-Nickel alloy deposit (55% Ni - 45% Fe) for welding
and repairing of spheroidal cast iron. Particularly recommended for steels/cast iron or pipe to flange welding in cast iron.
Good wash-in and flow of the weld metal. Principal advantage of this electrode : exceptional resistance against
overheating during welding due to the copper plated core wire. Exceptional welding characteristics. For foundry
defects, repairing of engine blocks, frame of tool machines, gearboxes, reducing, pump bodies, valve bodies.

Reduce the heat input to a minimum, keep temperature low (maxi temperature 70°C) in order to reduce
the risk of cracks in the base metal. Depose short beads of about 3 cm and peen immediately.
Reignite on the weld metal. Weld on clean and exempt from grease grease surfaces (previous grinding of the joint).
