The difficulty with welding characteristics of the cast iron generated majorly from the high carbon placid of the material. Due to welding and cooling, the carbon makes formation of various undesired micro-structures possible, reducing the weldability, a great deal in all regions related to welding. For welding the cast iron material by using warming welding process according to the preheating temperatures extent. the lower preheating temperatures are not sufficient for lowering the cooling rate to the desired values and hence formation of brittle phases as martensitic and carbides are encountered. Ni based electrodes are generally used for such cases. Ni based fillers are lame than steel alloys and yields higher ductility. Increased ductility modify crack formation especially in case of martensitic transformation and additionally Nickel bonds with Carbon preventing formation of iron carbide. Upon these superior properties, Ni electrodes provide relatively let down mechanical properties with respect to steel.
