摘　　要：针对风机塔筒焊缝的高空TOFD检测技术中容易出现爬行器在行走过程中难以保持焊缝对中而造成无法有效检测的问题,基于激光焊缝跟踪技术设计了一款激光跟踪传感器,并将其与塔筒焊缝TOFD检测技术相结合,形成能够有效保持焊缝对中的高空塔筒焊缝TOFD检测系统。同时通过跟踪效果测试验证了所设计的激光跟踪传感器具有良好的一致性,能够实现高空塔筒焊缝的自动跟踪、自动修正,自动检测等功能,保证了风机塔筒TOFD检测技术的有效运用。In view of the problem that the crawler is difficult to keep the weld alignment during walking,which is easy to occur in the high-altitude TOFD detection technology of wind turbine tower weld,this paper designs a laser tracking sensor based on the laser weld tracking technology,and combines it with the tower weld TOFD detection technology to form a high-altitude tower weld TOFD detection system that can effectively keep the weld alignment.At the same time,the effectiveness of the automatic detection of the tower by using the TOFD sensor is verified,and the automatic tracking of the tower can be achieved.
