Abstract :In this study, related to getting better obtain to the mechanical properties of medium carbon steel joints joined by MIG welding method using the Taguchi method welding groove were optimized. Grove angle insert ignore into journalissuearticles values(60ᵒ, 75ᵒ and 90ᵒ);, current insert ignore into journalissuearticles values(100 A, 110 A and 120 A); and voltage insert ignore into journalissuearticles values(25 V, 30 V and 35 V); were used as welding parameters. The results showed that the highest tensile strength as 597.963 MPa was obtained at groove angle 90ᵒ, current 120 A and voltage 30 V, the lowest tensile strength was obtained as 395.125 MPa. The highest elongation as 11.551% was obtained at groove angle 90ᵒ, current 120 A and voltage 30 V, the lowest elongation was obtained as 8.354%. In addition, it was observed that the changes in current and voltage values significantly affect the tensile strength and elongation values of the joints. According to ANOVA analyses, the most effective parameter on average tensile strength and elongation were determined to be groove angle insert ignore into journalissuearticles values(62.75% and 75.58%, respectively);. Based on S/N ratios, the optimal parameters for average tensile strength and elongation were determined A3B3C2 factors.
