Electrode provides Weld metal with 70% Ni and 30% Cu content about, suitable for the repair of broken or worn cast iron parts. Also suitable for filling blowholes of castings. Stable arc providing clean bead appearance. Electrode provides crack resistant bead without pore formation. Weld induced stresses can reduced by hammer peening. Machinable deposit.
Materials of application
Cast iron. Joining of grey cast iron to steel.
