The experimental study is carried out for the analysis of weld bead geometry such as bead reinforcement height, bead width and bead penetration of synergic MIG welding of 304L stainless steel. Microstructures of different zones of interest like weld metal, HAZ and fusion boundary under different welding parameters were viewed and captured with an optical microscope coupled with an image analyzing software. Fractured surface of the weld bead specimens were analyzed using Scanning electron microscopy (SEM) to the nature of the fracture mode. The results of EDS analysis shows that the inclusion particle mainly composed of Fe, Cr, Mn, Si, C elements. X ray diffraction (XRD) study has been done and result shows that phases like Fe, Ni-Cr-Fe, and Fe-Cr-Co-Ni are determined.
