| 摘 要： | 采用搅拌摩擦焊(FSW)和MIG焊分别对6061铝合金板进行了焊接试验,测试了焊接接头的强度,观察了焊接接头的金相组织,并进行了接头的硬度分布测试.结果表明,搅拌摩擦焊接头抗拉强度高达212.05 MPa,是母材抗拉强度的86％,比MIG焊的接头强度略高.焊接接头软化区宽度比MIG焊接头软化宽度窄.6061铝合金母材为典型的轧制组织,焊核区为细小的等轴晶组织,MIG焊接头焊缝为柱状晶组织.

| Abstract: | 6061 aluminum alloy plates were jointed by friction stir welding (FSW) and MIG welding. The mechanical properties of the joints were tested. The microstructure was observed. And the distribution of the hardness of the joints was also tested. The results showed that the tensile strength of the joint by FSW was 212.05 MPa which reached the 86.2% strength of the base material. The tensile strength of the joint by FSW was slightly higher than the joint by MIG welding. Softening zone of welded joints by MIG welding was wider. Base material of 6061 aluminum alloy was the typical rolling organization. Weld core zone was the equal -axle grain. The weld by MIG welding was cast structure. |
