| 摘 要： | 搅拌摩擦焊接方法在某些条件下也会造成焊接缺陷的产生,其中对接头性能有显著影响的缺陷包括沟槽、孔洞和未焊合.针对这三种类型的缺陷,用搅拌摩擦焊接方法进行补焊,以此研究补焊接头的焊缝成形和力学性能.结果表明,采用搅拌摩擦补焊方法能够消除沟槽、孔洞和未焊合等搅拌摩擦焊接缺陷;在优化的补焊工艺参数下,能够获得焊缝成形良好的补焊接头,其性能与优质原始接头的性能相当;补焊接头在拉伸测试中均在焊缝的后退侧发生断裂,拉伸断口具有明显的韧窝特征.

| Abstract: | Welding defects can be also formed during friction stir welding under improper welding technology conditions, and the friction stir welding defects such as groove, void and kissing bond significantly influence the mechanical properties of joints. Friction stir welding process is utilized to repair these defects, and the focus is placed on the weld morphology and mechanical properties of the repaired joints. The experimental results indicated that the friction stir welding process can remove the above-mentio... |
