本文对AA6061铝合金和SS400低碳钢异种金属进行了搅拌摩擦焊焊接试验，并确定了最佳的搅拌摩擦焊工艺条件。在异种金属搅拌摩擦焊对接过程中，有四个主要的可控因素，即搅拌头旋转速度、横向速度（进给速度）、搅拌头相对于工件表面的倾角和搅拌头直径。可以理解的是，并非所有的可控因素都包括在本文中。异种金属对接接头的质量是通过冲击值来评价的，文献中尚未讨论过。此外，还使用一个不可控的参数，即抗拉强度，根据出色的冲击值对其质量进行双重检查。采用方差分析（ANOVA）对实验数据进行分析。田口技术与方差分析也被用来确定性能特征的显着因素。研究结果可供水陆运输机械减重参考。
This research aimed to weld dissimilar metals joints, AA6061 aluminum alloy and SS400 low-carbon steel, and find the optimum operating conditions of friction stir welding. In dissimilar metals butt joint by friction stir welding procedures, there are four major controllable factors, which are tool rotation speed, transverse speed (feed rate), tool tilt angle with respect to the workpiece surface and pin tool diameter. Understandably, not all the controllable factors are included in this article. The quality of dissimilar metals butt joints is evaluated by the impact value, which has not been discussed in literatures. In addition, an uncontrollable parameter, which is the tensile strength, is used to double-check its quality based on the excellent impact value. Analysis of variance (ANOVA) is used to analyze the experimental data. The Taguchi technique with ANOVA is also used to determine the significant factors of performance characteristics. The results are expected to serve as references to overland and aquatic transportation machines for weight reduction.
