１引言我国河流泥沙含量大，建立在河流上的水电站所使用的水轮机存在严重的汽蚀、磨损等破坏，需要定期检修，以保证水电站正常运行。目前，在我国水轮机转轮叶片修复仍采用手工补焊，人工打磨，如能采用自动化设备进行补焊来代替手工操作，既能提高生产效率，缩短检修周期， 1 Introduction China’s river sediment content is large, the water turbine used in the hydropower station built on the river has serious cavitation, wear and tear and other damage, and requires regular maintenance to ensure the normal operation of the hydropower station. At present, the repair of turbine blades in our country is still using manual repair welding, artificial grinding, welding repair if instead of using automated equipment instead of manual operation, both to improve production efficiency and shorten the maintenance cycle,
