Typical applications and characteristics
GEMINI Ni 55 all positional electrode depositing at 55% Ni, 45% Fe weld metal designed specially for strength welding. Grey cast iron and malleable cast iron with steel. Also designed to operate at low current which minimizes heat input and thus facilitates the cold welding of cast iron. Weld induced stresses can be reduced by hammer peening. Stable are with clean head appearance. The weld metal is fully machinable
