Effect of Titanium/Reduced Graphene Oxide Nanocomposite as a New Filler on the Properties of Gas Tungsten Arc Welding of Titanium

Here, the effect of reduced graphene oxide (RGO) nanosheets on the microstructure and mechanical properties of titanium‐welded joints is investigated through gas tungsten arc welding (GTAW). The obtained results indicate that by increasing the RGO volume fraction up to 1.9%, due to the decreasing of the grain size and probably reinforcing the grains, the tensile strength and hardness of welding are improved up to 30% and 78%, respectively.
