摘要 采用拉锻式摩擦塞补焊方法对4mm厚的2014铝合金搅拌摩擦焊接头缺陷进行了补焊,焊后对塞补焊接头的微观组织和拉伸性能进行了分析。研究结果表明,摩擦塞补焊接头分为焊缝区、热影响区和母材区三部分,焊缝由细小的等轴再结晶组织构成。选择合适的焊接参数和接头结构,塞补焊接头的抗拉强度可以达到330MPa以上,达到或超过搅拌摩擦焊接头强度。塞补焊接头微观硬度分析表明,塞补焊后接头焊缝区硬度较高,但整体硬度变化不大。 Friction plug welding of 2014 Al alloy FSW joints in 4 mm thickness have been successfully completed. The metallurgy experiment demonstrates that the FPW joint microstructures could be divided into three different regions: welding line zone, HAZ and base metal zone. The dynamic recrystallization occurs in the welding line zone, which consist of refined, equiaxed grains. Mechanical property measurements demonstrate that the peak tensile strength of the joint can reach more than 330MPa, reach or exceed the joint strength of the FSW welding joint when the suited parameters were used. The microhardness analysis shows that the hardness of the welding line zone is higher than the other zones, but the changes of the FPW joint microhardness is not very acutely.
