| 摘 要： | 以2524-T3板材作为试验材料,研究了薄板的搅拌摩擦焊对接工艺,优化了对接焊的工艺参数,获得了焊接工艺窗口及最优工艺参数.在最优工艺参数下生产的对接焊件具有良好的质量外观,焊件的变形量和焊缝减薄量极小；焊件的X射线检测结果表明焊件内部质量良好,没有在照片上发现缺陷；金相组织分析显示,焊缝横截面组织均匀致密；焊接接头静力拉伸性能测试结果表明焊缝抗拉强度的平均为397 MPa,为母材抗拉强度的90.4％.

| Abstract: | Butt weld process of friction stir welding for thin slab are studied in this paper,2524-T3 plate are selected as testing materials.The joining process is optimized to obtain the window of weld process and the best process parameters.The butt weld produced in optimized process parameters have an excellent appearance,as the deformation and the thickness reduction of weld are little;X-ray inspection results show the inner quality of welds is good,and no defects are found in the picture;metallographic analysis ... |
