Abstract

As a new type of welding method for special equipment, T-weld has more and more wide application scope and prospects. At present, there is still no effective and reliable method for the quality inspection of this new type of structure. In view of the testing needs of T-shaped welds, this paper proposes the use of ultrasonic phase-controlled inspection methods for common defects such as root cracks, pores, unfused side grooves on the web, and unfused side grooves on the flanges of T-shaped welded joints. Welded joints were tested, and radiographic testing methods were used for comparison. The test results show that compared with other detection methods for T-shaped welds, the ultrasonic phased array detection technology has better reliability, and can accurately identify common defects such as cracks, lack of fusion, and pores in the T-shaped welds, which is the most important part of the later T-weld. The research on ultrasonic phased array detection of type welds has laid a certain foundation.
