摘要： PROBLEM TO BE SOLVED: To obtain an ultrasonic test method and an instrument therefor for the welded part of a steel pipe in which an erroneous detection due to aqueous paste, or the like, on the outer face side of the steel pipe is reduced, a detrimental flaw can be detected accurately and surely over the entire cross-section of the welded part using a small number of ultrasonic probes even in case of a thick material, and the ultrasonic probe group can be followed up by detecting the center of the welded part accurately while reducing the dead-band part at the opposite ends of the welded steel pipe.
SOLUTION: An ultrasonic probe 4 for detecting a longitudinal crack in the group of ultrasonic probes is arranged at the head so that the water in a contact medium of an ultrasonic probe 5 for detecting a lateral crack immediately above the welded part 2 is not detected erroneously when a flaw on the outer surface is detected by means of the ultrasonic probe 4. The ultrasonic probe 4 is a variable refraction angle probe, e.g. an array type probe, capable of detecting a longitudinal flaw on the inner surface or the outer surface or in the center of the welded part using a single probe. The leading end part and the trailing end part of the welded steel pipe are detected by means of a welded part detector 3 using two laser lights, and the welded steel pipe is carried at a low speed and followed up by the ultrasonic probe group at a high speed thus reducing the dead-band part at the opposite ends of the welded steel pipe.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic flaw detecting method capable of enhancing the detection precision of the flaw contained in the welded part formed in the axial direction of a welded steel pipe.
SOLUTION: A sample welded steel pipe, which is manufactured by the same molding process as a welded steel pipe to be inspected, has the same outer diameter as the welded steel pipe to be inspected and includes a flaw in its welded part, is prepared (S1). After an array probe is arranged on the outer peripheral surface of the sample welded steel pipe (S2), an ultrasonic beam is directly allowed to enter the flaw without being reflected from the outer and inner peripheral surfaces of the sample welded steel pipe (S3). The incident angle of the ultrasonic beam and the arranging position of an array probe are altered while outputting the ultrasonic beam, and the incident angle and the arranging position maximizing the echo of the flaw are determined from the altered incident angle and the arranging position (S4-S7). After determination, the sample welded steel pipe is replaced with the welded steel pipe to be inspected (S8) and the flaw of the welded steel pipe to be inspected is detected on the basis of the determined incident angle and the arranging position.

摘要： PROBLEM TO BE SOLVED: To surely prevent collision of an H beam against a flaw detection nozzle.
SOLUTION: In this method, flaw detection of a fillet part or a weld zone is performed by an ultrasonic wave (transmission echo) oscillated from ultrasonic probes 20a, 20b arranged separately from upper and lower flange 11aa, 11ab faces of the H beam 11, respectively. An observation gate G3 of a surface echo R reflected by the flange 11aa, 11ab faces on the transmission echo incidence side is provided on a prescribed position in the time base direction starting from the transmission echo T, and a reflected echo of the transmission echo T is observed by the observation gate G3. The reflected echo having a level higher than a prescribed value and nearest to the transmission echo T on the time base among the reflected echoes is recognized as the surface echo R. When the recognized surface echo R vanishes to the start end side of the observation gate G3, the ultrasonic probes 20a, 20b are rearranged farther from the flange 11aa, 11ab faces.
