Cast iron is a group of carbon iron alloys with carbon percentage greater than 2%. As we seen that ductile cast iron have spheroidal graphite flakes, nodules which stops crack from further processing. Welding is the process of joining two metals by means of fusion. An electrode is mainly used to bearing the current through a workpiece to accomplish two pieces together depending upon the processes. Electrode either consumable in case of MIG welding, SMA welding etc. or non consumable in case of TIG welding. The nickel based electrode is widely used to weld cast iron due to its high mechanical strength corrosion resistance, etc. Keywords: cast iron, welding, nickel based electrode, strength.
