Effect of cladding of stellite-6 filler wire on the surface of ss316l alloy through cold metal arc transfer process

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