[0002] At present, non-destructive testing of welds is an important means to ensure the safety of welded structures. Ultrasonic testing, as a major method of non-destructive testing of welds, is widely used due to its non-destructiveness, high precision and wide applicability. The ultrasonic array oblique-incidence longitudinal wave test block is a test block used for ultrasonic testing, which is mainly used to test and calibrate the performance of ultrasonic testing equipment and probes.
