なかった。Conventionally, when performing ultrasonic flaw detection on internal defects in cylindrical test materials, such as cast pipes, etc., one probe was brought into contact with the surface of the test material, and the position was sequentially changed. However, flaw detection was performed manually. Therefore, there were drawbacks such as poor working efficiency and lack of reliability. In addition, if an internal defect has directionality, it is not possible to reliably identify the defect with a single test using a vertical or oblique probe, and conventionally, it has been difficult to identify the defect by changing the probe. then 4
It is normal to repeat deep scratches ~5 times, and it is not possible to detect all directional internal defects in one operation.

記録紙に記録しておくこともできる。Next, the operation of the above configuration will be explained. When testing the test material (1), first, the test material +11 on the mount (3) is rolled in the direction of the arrow a and sent to the position of the receiving roll (8). Then, when the material to be inspected (1) reaches the position of the receiving roll (8), the lifting platform (
4) as shown by arrow B, and place the specimen (
1) is rotatably supported by a receiving roll (8) of a movable table (9). Next, the hydraulic cylinder θ is extended and the pair of movable bases (9) are moved laterally as shown by arrow C while supporting the specimen (1), and one end of the specimen i1 is moved. The flange part (2) is brought into contact with the scroll chuck (1), and the flange part (2) is
), the drive device α barrel is activated to pick up the test material (1
Rotate 1 around the axis. When the material to be inspected f41 starts to rotate, the flaw detection head is lowered onto the material to be inspected (1), and while the traveling frame (19) is traveling, flaws are detected sequentially from one end side of the material to be inspected +1). In this case, each probe of the flaw detection head (2) is moved in the vertical direction ('V), in the opposite axial direction (L) (R), and in the opposite circumferential direction CB') (B ) By transmitting ultrasonic waves at the same time or with a slight time lag, it is possible to perform flaw detection in five directions almost simultaneously, and even directional internal defects can be detected immediately and reliably, improving reliability and making work easier. Efficiency is significantly improved. When flaw detection is completed,
Lift the flaw detection head, stop the drive device (11), release the grip by the armpit 6 scroll chuck, retract the hydraulic cylinder +6) (t12), and move the test material +1+ in the opposite direction to the above. It is returned to the pedestal (3) and sent out by rolling on this pedestal (3). The flaw detection results can be monitored with a monitor television trowel during the flaw detection, and can also be recorded on recording paper using the recorder 071.

The marking device activated by the defect signal marks the material to be inspected.
A marking may be attached to the defective position.

They may be arranged in a row. However, in order to perform flaw detection up to the end of the test material fi+ under the same conditions, it is preferable to arrange them in a line in the circumferential direction.

Work efficiency and reliability are improved. Further, since the flaw detection head is provided so as to be movable relative to the material to be inspected in the axial direction and the circumferential direction, it is possible to mechanize and automate the work.
