Resisting Corrosion under Chloride Environment by Providing Duplex Stainless Steel Cladding Through FCAW

Cladding is one of the solutions usually resorted to protect a structure from the detrimental effect of its surrounding environment. This investigation concerns with covering of duplex stainless steel on low carbon steel through flux cored arc welding (FCAW) under different parametric settings. Microstructure is observed and corrosion test under chloride environment is undertaken to find out resistance to corrosion of cladding. Corrosion becomes quite low at 0.38 IO/mm heat input. At this condition, welding speed was also at a higher side. Therefore, the corresponding combination of parameters would be adopted for getting extended service life of a structure.
