摘要：

The control factors including rotating speed, welding speed and plunge depth of 6005A-T6 aluminum alloy friction stir welding were optimized by Taguchi method, and the combined effects of these factors were comprehensively investigated. Statistical results were analyzed by the analysis of variances and signal-to-noise ratios. The results show that the rotating speed is the most dominant factor in determining the joint tensile strength; and the plunge depth and welding speed are the second and third effective parameters, respectively. Under the optimum process parameters, the joint maximum tensile strength reaches 239.6 MPa which is 84% of that of the base material. The relationships between the main control factors, thermal cycle, formation, microstructure, mechanical properties and fracture characteristics were investigated.
