Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to an automatic grinding device for pipeline phased array ultrasonic detection. Background Art

[0002] The characteristics of the phased array fully automatic ultrasonic detection method for pipeline girth welds are: using a group of probes to replace a single probe, automation to replace manual operation, fast detection speed, and the ability to determine the height of the defect itself. The fully automatic ultrasonic has a lower rework rate. The presence of rust, oxidation, dust and other impurities on the surface of the pipeline will affect the propagation and reflection of the ultrasonic wave and reduce the accuracy of the detection. Therefore, these impurities need to be removed by grinding before detection to improve the propagation and reflection of the ultrasonic wave, thereby improving the accuracy of the detection.
