Abstract
The characteristics of the ultrasonic testing process of the hot-melted butt joint of PE pipes by the diffraction time difference method were studied. The artificial defect samples and the actual defects on site were tested, and the reliability of the process was verified. The results show that the diffraction time difference ultrasonic testing technology can reliably detect the typical defects in the hot-melted butt joints of PE pipes.
