The Mechanical Properties of 6061-T6 Aluminum Alloy Joints Joined by MIG Welding Method (TPS/i) Using Different Shielding Gas Flow Rates

In this study, aluminum 6061-T6 alloy sheets with a thickness of 3 millimeters were welded using the TPS/i MIG welding process. Welded samples were joined in the shape of butt joints. Argon was used as the welding shield gas, and the welded joint procedures were carried out at various shielding gas flow rates. Tensile strength and hardness values of the welded 6061-T6 aluminum alloy sheets were determined, and their microstructure and macrostructure were investigated using an optical microscope. The weldability of 6061-T6 aluminum sheets was investigated using the MIG welding process (TPS/i), and the impact of various shielding gas flow rates on mechanical parameters, macrostructures, and microstructures was studied.
