Nickel-Arc 99 is designed for welding
gray, malleable and nodular cast iron. The electrode utilizes a pure nickel core
wire. This is particularly
important when welding on overlay of cast iron where a high nickel deposit is
required. Machining is possible with this electrode.
Proper welding procedures should be followed. Nicore

The Nicore 55 is a unique “wire-within-a-wire”
composite metal cored electrode developed to join or repair a variety of cast
irons. The deposit
consists of approximately 50.5% iron and 48% nickel, permitting expansion during
welding. Thermal stresses are minimized
due to the less frequent stops and starts previously associated with covered electrodes.
Operating on 98% argon/2% oxygen
shielding, this wire will produce a 97% deposition efficiency.
