Description

Phased array detector for storage tank detection

Technical Field

The utility model relates to the technical field of nondestructive testing, in particular to a phased array detector for storage tank testing.

Background

At present, the ultrasonic phased array detection technology is widely applied to weld defect detection. In the detection process of the welding seam of the storage tank, if the relative position of the ultrasonic probe and the welding seam is changed, the size and the position of the welding seam defect are greatly influenced.

Generally, the welding seam defect detection adopts a manual operation mode. An operator places the scanning frame provided with the probe on the surface of a test piece to be detected, pushes the scanning frame to walk at a constant speed along the length direction of a welding line by hands, transmits a probe signal to the phased array instrument in real time, and can know the structure and the position of a defect through a scanning map on the instrument. The traditional manual detection has high labor intensity and low efficiency. Meanwhile, if the trend of the welding seam is obviously changed in the operation process, the operation of manually adjusting the position of the probe is complicated, and the accuracy of the relative position between the probe and the welding seam is difficult to ensure. With the rapid development of the welding seam detection technology to the automation direction, it is necessary to design an ultrasonic phased array welding seam detection scanning frame capable of realizing electric position adjustment so as to meet the requirement of automatic welding seam detection.
