This study compared the microstructure and mechanical characteristics of AA6061-T6 joints produced using friction stir welding (FSW), friction stir vibration welding (FSVW), and tungsten inert gas welding (TIG). FSVW is a modified version of FSW wherein the joining specimens are vibrated normal to the welding line during FSW. The results indicated that the weld region grains for FSVW and FSW were equiaxed and were smaller than the grains for TIG. In addition, the weld region grains for FSVW were finer compared with those for FSW. Results also showed that the strength, hardness, and toughness values of the joints produced by FSVW were higher than those of the other joints produced by FSW and TIG. The vibration during FSW enhanced dynamic recrystallization, which led to the development of finer grains. The weld efficiency of FSVW was approximately 81%, whereas those of FSW and TIG were approximately 74% and 67%, respectively.

这项研究比较了使用搅拌摩擦焊（FSW），搅拌摩擦振动焊（FSVW）和钨极惰性气体保护焊（TIG）制成的AA6061-T6接头的组织和力学性能。FSVW是FSW的改进版本，其中在FSW期间，连接试样垂直于焊接线振动。结果表明，FSVW和FSW的焊接区域晶粒是等轴的，并且比TIG的晶粒小。此外，与FSW相比，FSVW的焊接区域晶粒更细。结果还表明，FSVW生产的接头的强度，硬度和韧性值高于FSW和TIG生产的其他接头。FSW期间的振动增强了动态再结晶，从而导致了更细晶粒的发展。
