Filler materials used to weld ductile cast iron – A review

Austempered ductile iron (ADI) is a new engineering material type which continue receiving increased attention in research and industry. Extensive conducted so far has demonstrated that ADI excellent property combination such as high strength-weight ratio, ductility toughness, good fatigue strength, damping properties wear resistance. As result of to their exceptional mechanical mix, fabrication simplicity, low cost lowest weight per unit strength ratio compared common steels, this family ferrous cast alloys have begun replacing forged steels some applications. However, major limiting factor widespread use manufacturing industry remains its weldability, more especially during process. Current work presents review various filler materials (electrodes) used weld using two industrial welding processes, namely, shielded metal arc (SMAW) gas tungsten (GTAW). The successes well short-comings these electrodes on weldability been recorded clear need for an improved identified.
