Abracast 12 S
Ferro nickel electrode core wire copper coated
Description & applications
Graphite-basic coating with a copper coated core wire and a Ferro-Nickel alloy deposit (55%Ni - 45%Fe) for welding and repairing of nodular 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.
Main application: For foundry defects, repairing of engine blocks, frame of tool machines, gearboxes, reducing pieces, pump bodies, 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 –not on the casting.
