[0024] During use, hold the grip 1, then put the support ring 2 and the rotating ring 4 on the outer wall of the pipeline, and then let the device slide on the outer wall of the pipeline through the sliding component 6. When moving to the welding position to be detected, turn on the driving component 7 to drive the rotating ring 4 to rotate, and then turn on the X-ray detection head 5, and the welding position can be detected in an all-round circumferential manner.

Next, with the support of the moving wheels 604, the device slides smoothly on the outer wall of the pipeline. When the device is moved to the welding position to be detected, push the push block 707 to drive the push plate 701 to move forward. At this time, the cooperation of the rack 702 and the gear 704 drives the pulley 703 to rotate. Then, the rotating ring 4 is driven to rotate 90° through the belt groove 705. Next, drive the push plate 701 to move backward by the push block 707 to return the rotating ring 4 to its initial position. At this time, the four X-ray detection heads 5 on the inner wall of the rotating ring 4 can achieve an all-round circumferential detection of the welding position.
