Abstract : The current study explores the effect of Overalloyed filler wire (ERNiCrMo-17) on the weldments of alloy C-276 fabricated through pulsed current tungsten inert gas welding (PCTIG) and tungsten inert gas welding (TIG) technique. The optical microstructure shows that current pulsing technique obtained the refined equiaxed microstructure compared to TIG coarse cellular structure. From Scanning electron microscope (SEM), it is identified that secondary precipitates are absent in the boundary zones of the weld zone. Energy dispersive spectroscopy (EDS) confirmed that microsegregations were absent in between the grain and boundary regions. The results of the tensile test verified that fracture was occurred in the base metal, not in the fusion zone.
