Abstract

In this study, synergistic double-sided friction stir welding (DS-FSW) is proposed to solve the problems of large deformation and the time-consuming of traditional DS-FSW. The microstructure, mechanical properties, and fracture paths of novel and conventional joints are studied under different welding parameters. Results show that defects in novel joints have been improved. However, the grain size in the stir zone of novel joints is larger than that of conventional joints. The microhardness map of the novel joint shows a more uniform distribution compared to that of the conventional joint. At a rotational speed of 1800 rpm and transverse speed of 1000 mm min−1, the distortion of the novel joint and conventional joint is 0.1 and 1 mm, respectively. The tensile force of novel joints is higher than that of conventional joints for the same welding parameters. The maximum tensile force of novel and conventional joints is 36.8 and 34.9 kN, respectively.

6061-zxalumium合金常规和协同双面FSW接头组织和力学性能的比较研究

为了解决传统搅拌摩擦焊变形大、耗时长的问题，提出了协同双面搅拌摩擦焊（DS-FSW）。研究了新型和传统接头在不同焊接参数下的组织、力学性能和断裂路径。结果表明，新型接头中的缺陷得到了改善。然而，新型接头搅拌区的晶粒尺寸大于传统接头。与传统接头相比，新型接头的显微硬度图显示出更均匀的分布。转速为1800 rpm和1000的横向速度毫米 min−1，新型接头和传统接头的变形分别为0.1和1 mm。在相同的焊接参数下，新型接头的拉力高于传统接头。新型和传统接头的最大拉力分别为36.8和34.9 kN。

期刊介绍： Science and Technology of Welding and Joining is an international peer-reviewed journal covering both the basic science and applied technology of welding and joining. Its comprehensive scope encompasses all welding and joining techniques (brazing, soldering, mechanical joining, etc.) and aspects such as characterisation of heat sources, mathematical modelling of transport phenomena, weld pool solidification, phase transformations in weldments, microstructure-property relationships, welding processes, weld sensing, control and automation, neural network applications, and joining of advanced materials, including plastics and composites.
