Investigation of Weld Quality for Friction Stir Welding of Extrued 6XXX Series Aluminium Alloys
Özet
In this study, AA6082 and AA6005 aluminium alloys were joined using different rotation speeds (1200, 1500, and 1800 rpm) and feed rates (70,110, and 150 mm/min). Microstructures of welding joints were examined by an optical microscope and a scanning electron microscope (SEM). The surface fractures and possible welding defects were scanned via SEM. The best mechanical properties were obtained when conical helical shape stirrer pins were used. © 2021, The Minerals, Metals & Materials Society.
