摘　　要：针对多泥沙河流上运行的水轮机活动导叶修复问题，研究并完成了满足导叶堆焊和磨削的自动堆焊及磨削成套设备。现场使用情况表明：利用自动带极堆焊的方法，在磨蚀导叶的曲面上得到了光滑平整的耐磨金属层，使修型磨削量仅为手工堆焊的1/4；采用离线编程的方法使堆焊、磨削操作机和导叶旋转驱动机构的各向运动有机组合，得到了近于理想型面曲线的运动轨迹，使磨削曲面的误差小于0.2 mm，符合导叶修复的质量要求。For repairing the hydraulic turbine guide vane running in river filled with a great number of sand soil, the strip overlaying and grinding set have been reseached and manufactured. The result on_the_spot shows that: After using the process of strip auto_overlaying, the smooth deposited metal layer have been abtained on cured surface of the damaged guide vane and the revised_shap work was as 1/4 as by manual grinding; By the method of off_line programming, the approach ideal movement tracks were abtained by control the movement of the strip_overlaying(grinder) manipulator and the precision of the grinded cured surface was less then 0.2mm, meeting the repairing hydraulic turbine guide vane.
