Is considered the premium type, which works perfectly on cast iron with low phosphorus contents. Choose nickel filler wire for tig welding cast iron. Finally, the weld metal has good machinability.

I have some 3/32 nickel 99 rod, but i am not sure if i should use that or the stronger nickel 55 rod? Pure nickel will produce a softer, more malleable weld deposit. Preheating and slow cooling of the component is the crux for the cast iron welding procedure.

Because of the used material on it, this rod comes as a cheaper option. There are two common types of nickel rods: Heat the piece of cast iron.

Mig nickel wire is expensive but can be used with 80% argon, 20% carbon dioxide gas. This rod doesn’t shrink much and has high tensile strength and ductility (elasticity). 55% nickel, 45% iron mix:

The flux material combined with the wire deposit weld metal high in nickel, iron, and carbon to repair gray and ductile irons but also weld cast iron to steel. The weld deposits produced by washington alloy nickel 99 have lower strength and ductility than those of 55% nickel cast iron electrodes.
