EXPERIMENTAL RESEARCH OF INTEGRATED ULTRASONIC TECHNOLOGY OF PHASED ARRAY AND TOFD FOR DETECTING PIPELINE DEFECTS

摘要：

A segment of pipe was made up with various kinds of welding defects for experimental research. The pipe was inspected by an ultrasonic system using integrated technology of phased array and time of flight diffraction (TOFD). All the echo feature of different defects such as crack, corrosion, lamination etc. was analyzed. The experiment results shows that the integrated technology of phased array and TOFD has satisfying reliability and high precision. Other methods such as normal ultrasonic measurement and x-ray radiography technique were also used to compare with and verify the results gained by the integrated ultrasonic phased array and TOFD technique.
