[0002] With the rapid development of phased array technology, ultrasonic testing using phased array ultrasonic probes has become more efficient and reliable, and has become the preferred non-destructive testing method in the industry. When working, the phased array probe converts electrical signals into ultrasonic waves and transmits them to the flaw detector to convert them into defect signals. The whole process is very fast and the test results are very accurate.

[0003] In the existing phased array ultrasonic testing of pipelines, a manual handheld probe is usually used. The manual handheld probe may cause the distance between the probe and the pipeline to be unstable due to hand shaking or maintaining the same action for a long time, and it is easy to cause fatigue.
