  • The current article compares the microstructure and mechanical characteristics of AA6061-T6 joints made by friction stir welding (FSW), friction stir vibration welding (FSVW), and tungsten inert gas welding (TIG) processes. FSVW is a modified version of FSW in which the joining specimens are vibrated normal to the welding line while FSW is carried out. The results indicated that weld region grains for FSVW and FSW were equiaxed and they were smaller than grains for TIG and additionally, weld region grains for FSVW were finer than those for FSW. The results also showed that strength, hardness, and toughness values of joins made by FSVW were higher than those of other joints made by FSW and TIG. It is believed that vibration during FSW enhances the dynamic recrystallization (DR) and as a result, finer grains are developed. The weld efficiency of FSVW is approximately 81%, whereas this ration is about 74% and 67% for FSW and TIG, respectively.

Abstract: The current article compares the microstructure and mechanical characteristics of AA6061-T6 joints made by friction stir welding (FSW), friction stir vibration welding (FSVW), and tungsten inert gas welding (TIG) processes. FSVW is a modified version of FSW in which the joining specimens are vibrated normal to the welding line while FSW is carried out. The results indicated that weld region grains for FSVW and FSW were equiaxed and they were smaller than grains for TIG and additionally, weld region grains for FSVW were finer than those for FSW. The results also showed that strength, hardness, and toughness values of joins made by FSVW were higher than those of other joints made by FSW and TIG. It is believed that vibration during FSW enhances the dynamic recrystallization (DR) and as a result, finer grains are developed. The weld efficiency of FSVW is approximately 81%, whereas this ration is about 74% and 67% for FSW and TIG, respectively.
