In this article, the current and gas flow rates were varied using Taguchi’s experiment design. The mechanical properties of the welded joint made using tungsten inert gas (TIG) welding and Ti6Al4V ELI as filler metal was characterized using the microstructure, microhardness, and tensile strength. The joint was classified into three regions, namely, fusion zone (FZ), heat affected zone (HAZ), and base metal (BM). Results show martensitic microstructure within the fusion zone (FZ) and the heat affected zone (HAZ), which resulted in an increased hardness within the fusion and heat affected zone.}, type={Article}, title={TIG Welding of Ti6Al4V: Effect of Ti6Al4V ELI as Filler Metal}, URL={http://www.czasopisma.pan.pl/Content/127417/PDF/AMM-2023-2-44-Omoniyi.pdf}, doi={10.24425/amm.2023.142460}, keywords={Fusion welding, microhardness, tensile strength, Ti6Al4V, TIG}, }
