Abrafonte 2
Pure nickel electrode
Description & applications
Electrode with graphite-basic coating to weld on DC - and AC. Weld deposit consists of pure nickel. Recommended for cold welding and repairing of grey cast iron, repairing of cracks. Homogeneous and easy to machine deposit. Good bonding and flow of the weld metal.
Main applications: Repairing of engine blocks, frames of tool machines, gearboxes, reducing pieces, valve and pump bodies.

Welding Instructions
Weld on clean and exempt from grease surfaces (previous grinding of the joint). Apply a heat input as low as possible and keep the temperature low ( < 70°C). Weld with lowest practical current and depose short and narrow beads to reduce the risk of producing cracks in the base metal. To reduce stresses, produced during welding, hammering of the beads is recommended after the deposition of short runs (essential on rigid pieces).
