Ultrasonic detection tool for welding seams of four pipelines of boiler

The utility model belongs to the field of ultrasonic detection of welding seams of four pipelines of a boiler, and discloses an ultrasonic detection tool for the welding seams of the four pipelines of the boiler. The device comprises a detected pipe fitting axial track, an annular track motor, an axial track motor, a track connecting device, an ultrasonic detection probe, a detection probe and axial track connecting device and a detected pipe fitting. Wherein the circumferential track motor and the circumferential track enable the axial track to move along the circumferential position of the detected pipe fitting, and the axial track motor and the axial track enable the ultrasonic probe to move along the axial position of the detected pipe fitting, so that the ultrasonic detection probe can perform multidirectional detection on the pipeline welding seam of the detected pipe fitting in the axial direction and the circumferential direction, and the welding quality of the pipe fitting is ensured. 本实用新型属于锅炉四大管道焊缝
