Abstract
According to the uncertainty factors of deviation phenomenon appeared in SAWH pipe production process, it studied spiral welded pipe weld automatic tracking system based on CCD image recognition technology. In this article, it introduced the working principle, hardware composition and software design. The weld automatic tracking system consists of CCD sensor, image acquisition, motion control, I/O interface board, industrial computer, AC servo motor and so on. The software design mainly include some control modules, including image acquisition display, image processing recognition, motion control, Logic control signal input and output. The installation, debugging and commissioning for this system were conducted in certain SAWH pipe production line. The actual tracking results indicated that the welding head can track the center position of weld in time, control the weld offset error within a prescribed scope, reduce welding defects, and meet production requirements.关键词
