Description
Technical Field

[0004] Among them, according to different coupling methods, ultrasonic testing of pipe materials can be divided into contact method testing and immersion method testing. Contact method testing refers to a method in which an ultrasonic probe is in contact with the surface of the pipeline to be tested through a thin-layer coupling medium; this method is usually manual testing, with low detection efficiency and flexible operation, and is suitable for single-piece and small-batch testing. Immersion testing is to place an immersion longitudinal wave probe in water. When the longitudinal wave is obliquely incident on the water / steel interface and the incident angle is within a certain range, only pure shear waves are retained inside the steel pipe for testing; the sensitivity of immersion testing is high, the testing speed is fast, and it is convenient to realize automated testing.
[0005] Specifically, when carrying out pipeline immersion testing, the detection parameters that need to be key-controlled are the water layer thickness H and the eccentricity X. Among them, the water layer thickness H refers to the distance from the immersion longitudinal wave probe to the pipeline surface, and the eccentricity X refers to the horizontal distance between the beam axis of the immersion longitudinal wave probe and the central axis of the pipe material. During the implementation of immersion testing, ensuring the stability of the water layer thickness H and the eccentricity X is the key to ensuring the detection result; after determining the water layer thickness H and the eccentricity X according to parameters such as the outer diameter and wall thickness of the pipeline to be tested, how to quickly determine the probe placement position and how to ensure the controllability and measurability of the probe position during the testing process are the key links to improve the detection efficiency and ensure the detection quality.
[0006] However, the inventor found that there is currently a lack of a probe positioning device for the pipeline immersion focusing testing process to be able to quickly determine the water layer thickness H and the eccentricity X during testing.
