Cast Iron Electrodes

The most common arc welding electrodes for grey cast iron are nickel and nickel-iron types. These electrodes have been used with or without preheating and/or post weld heat treatment. Cast iron and steel electrodes must be used with high preheats (550°C) to prevent cracking and the formation of hard deposits.
Child material class: Ductile iron; Gray iron; Malleable iron

99% Nickel

Nickel 99 welding electrode is designed for welding gray iron castings to themselves as well as joining them to mild or stainless steels. It is also used to repair castings. With the high nickel content, the welds are easily machined.
porosity free, crack and corrosion resistant.

55% Nickel

Nickel 55 stick welding electrode is designed for welding gray iron castings to themselves as well as joining them to mild steel. It can also be used to repair castings. The welds are moderately hard and require carbide tipped tools for post weld machining.
