| Abstract | In this work, Cladding was done on SS316L alloy through the CMT process using Stellite-6 filler wire. 31 experiments were done at different welding conditions as per CCD matrix. The cladding specimens were characterized by macro and micro-study, Vickers microhardness evaluation and corrosion resistance analysis. An optical microscope, SEM-EDAX, and XRD were used to predict the structural characterizations, presence and the distributions of the elements. Based on the study higher voltage and welding speed showed appreciable hardness at the interface & cladding regions. The thickness of the interface was noted at a maximum of 190 ?m. The EDS spectra showed that Fe, Cr and Co were the major elements in the clad and interface regions. The Co-rich phase and the low content of element O are found in the low corroded regions on the specimen. The maximum hardness observed at cladding and interface were 378 Hv and 270 Hv respectively. |
