Optimizing Fusion Zone Grain Size, Hardness and Tensile Strength of Micro Plasma Arc Welded Titanium (Ti-6Al-4V) Alloy Using Grey Relational AnalysisBy A. Sunny Kumar, T.V. Hanumantha Rao, V.V. Kesava Rao
Abstract: In the present work, Titanium (Ti-6Al-4V) alloy sheet of 0.5 mm thick is butt welded using Micro Plasma Arc Welding. Welding input parameters like peak current, base current, pulse rate and pulse width are considered and output responses like fusion zone grain size, hardness and ultimate tensile strength of the welded joint are considered. Taguchi L25 orthogonal matrix is adopted by considering four factors and five levels of weld input …
