SIGNAL ANALYSIS OF ULTRASONIC SYSTEM WITH PHASED ARRAY AND TOFD TECHNIQUE APPLIED ON INSPECTING PIPELINE WELDS DEFECTS

摘要：

The integrated ultrasonic technology of phased array and time of flight diffraction (TOFD) was used to inspect pipelines with typical defects such as cracks, lack of fusion, pores etc. The signal gained by A-Scan, B-Scan and S-Scan methods was analyzed and explained. The respective image feature of various defects was studied which provide a theoretical basis and practical experiences for inspecting pipeline welds defects.
