摘要

针对常规顺序双面搅拌摩擦焊接（DS-FSW）的变形大、耗时长等问题，提出了一种协同双面搅拌摩擦焊接（SDS-FSW）技术，并通过研制的设备研究了SDS-FSW 6061铝合金接头的微观组织和力学性能。结果表明，当主轴转速为1 800 r/min，焊接速度为1 200 mm/min时，SDS-FSW焊接接头缺陷较相同焊接参数下DS-FSW接头的有所改善；在该焊接参数下，SDS-FSW接头的变形量（0.15 mm）远小于DS-FSW接头的变形量（1 mm），且接头的拉伸性能更好，SDS-FSW和DS-FSW接头的最大拉力分别为36.8 kN和34.9 kN。

Abstract

In this study, aiming at solving the problems of large deformation and time-consuming of conventional double-sided friction stir welding (DS-FSW), synergetic double-sided FSW (SDS-FSW) was proposed. The microstructure and mechanical properties of the SDS-FSW 6061 aluminum alloy joints were studied by the developed special equipment. The results show that when the rotational speed is 1 800 r/min and the traverse speed is 1 200 mm/min, compared with the DS-FSW joint, the defects of the SDS-FSW joints are improved under the same welding parameters. The deformation of the SDS-FSW joint (0.15 mm) is much smaller than that of DS-FSW joint (1 mm) at this welding parameter. And the tensile performance of the SDS-FSW joints is better. The maximum tensile forces of SDS-FSW and DS-FSW joints are 36.8 kN and 34.9 kN, respectively.
