Description

technical field

[0001] The present application relates to the technical field of non-destructive testing, in particular to an ultrasonic testing system and a water immersion testing method. Background technique

[0002] At present, ultrasonic testing equipment is mainly used for non-destructive testing of workpieces. According to the propagation law of ultrasonic waves in the medium, sound waves propagate in the workpiece to be tested. If material changes or defects occur, the original propagation characteristics will be changed, resulting in reflection , refraction and wave conversion phenomena, and the propagation energy of ultrasonic waves will be redistributed. In order to improve the accuracy of flaw detection during the detection of common workpieces with a flat surface, the sound waves emitted by the ultrasonic probe should be perpendicular to the defect orientation.

[0003] However, for arc-shaped workpieces or workpieces with arc surfaces, traditional ultrasonic t...
