摘　　要：探讨了3mm厚5A06铝合金VPPA的焊接穿孔工艺。通过试验,获得了薄板铝合金VPPA的焊接工艺参数,焊缝外观一致性较好。经X射线无损检测表明,VPPA接头无缺陷,焊接质量良好。焊接过程中,焊缝中心线5mm外温度<120℃,焊接热输入集中。采用VPPA焊接而成的2m筒段,母线直线度均<2mm,薄板VPPA焊接变形控制效果明显。The welding hole technology of 3 mm thickness 5A06 aluminium alloy VPPA welding joint is examined. The weld parameter range is researched by test, and shapely weld is obtained. The fault isn＇t found in VPPA weld by X-ray NDT, and weld quality is favorable. In the weld course, the temprature is under 120 ℃ outward in 5 mm weld center field, 2 m diameter cylind is made by VPPA. Its generatrix is under 2 mm, and the distortion control effect of laminose aluminium alloy is evident.
