PROBLEM TO BE SOLVED: To provide a highly reliable inspection result by mounting a device body on a tubular member forming a circumferential seal weld part to be inspected, and scanning and inspecting the circumferential weld part by an inspecting probe. SOLUTION: Two probe raising and lowering mechanisms 70 are arranged on a rotating frame 61 with a circumferential space, and probes 80 are mounted on the lower. ends thereof. The probe raising and lowering mechanism 70 can move a probe support shaft 77 vertically by regulating the feed and discharge air quantity. The probe 80 has a tensile spring 87, so that a sensor 81 is pressed, in inspection, to a canopy seal part 11 having a dome-like section to hold a proper position. A body 30 is arranged around the canopy seal part 11 to be inspected, and fixed by a clamp mechanism 40, whereby the canopy seal part 11 can be inspected. Since the sensor 81 is pressed onto the canopy seal part 11 and moved along it when the height of the sensor 81 is regulated by the probe raising and lowering mechanism 70, and the rotating frame 61 is circumferentially driven by a rotating mechanism, flaw detection data can be provided. |
