Machine Learning-Based Prediction of Tensile Strength and Hardness in GTAW-Welded IS 2062 E250 Mild Steel Under Varying Heat Input
Gas Tungsten Arc Welding (GTAW) joints in structural mild steel exhibit a nonlinear, current-dominated relationship between tensile strength, hardness, and heat input that is difficult to capture using classical linear regression. A 16-run Taguchi L16 experimental design was conducted on IS 2062 Grade E250 mild steel (...
