    Micro Plasma Arc Welding of Similar and Dissimilar Materials and Formability Study of Welded Joint
    (2025) Haldar, Vivekananda
    This research focuses on the similar and dissimilar joining of austenitic stainless steel (316L) and Inconel 625 using Micro Plasma Arc Welding (MPAW). The study evaluates joint metallurgy and investigates its impact on the formability of welded blanks. Welding experiments with varying parameters are conducted to optimize joint strength and formability. Advanced characterization techniques, including XRD, TEM, and FESEM, are employed to analyse microstructures and phases in the fusion zone. The solution heat treatment improves formability by reducing dislocation density and dissolving secondary phases.
