走査で探傷する方法がとられていた。``Prior technology'' Two ultrasonic probes are used to inspect planar internal defects such as cracks, poor penetration, and poor fusion that occur in welded parts of thick steel plates used in pressure vessels and large structures. The most effective method is ultrasonic angle flaw detection using a probe. As is well known, ultrasonic angle flaw detection using two probes differs from the commonly used ultrasonic flaw detection in which transmission and reception are performed using a single probe. This is done using two probes: a reliable probe and a receiving probe. Methods for scanning with these two probes include tandem scanning, in which the two probes are scanned in tandem, and straddling scanning, in which the two probes are scanned in a V-shape across the inspection site. Conventionally, there was no suitable scanning tool for cross-scanning, so the probe was placed manually and scanned, or the weld excess was scraped off to make a flat surface and then tandem scanning was performed using the scanner of an ultrasonic flaw detection device. A method of detecting flaws was used.

る。 The scanner of this conventional ultrasonic flaw detection device has a chain 102 wound around a chain wheel 101 attached to both ends of a single arm C, as shown in FIG. By attaching the receiving probe 103b to the other side of the probe 103a and moving the chain 102, the two probes 1
03a and 103b are configured to linearly move in opposite directions along a track rod provided on arm C.

る。``Problem to be Solved by the Invention'' This conventional scanner has the disadvantage that it can only perform tandem scanning because the two probes simply move in a straight line along a straight trajectory. Furthermore, with conventional scanners, setting the standard sensitivity of the probe, which is adjusted before performing tandem scanning, is complicated. In other words, the standard sensitivity setting is performed by arranging the transmitting probe and the receiving probe so that the transmitting and receiving directions of the ultrasound waves face each other, and using the received sound level as a reference, but tandem scanning During flaw detection, scanning flaw detection is performed so that the transmission and reception directions of the two probes are in the same direction (both forward). Therefore, when setting the reference sensitivity, the probe must be removed from the scanner and installed in a different direction, and then for scanning flaw detection, the probe must be removed from the scanner, changed in the orientation, and installed again. There is the complexity of not having to do this. Furthermore, conventional scanners not only cannot perform cross-scanning as shown in Figure 5, but also cannot have the transmitter and receiver probes lined up vertically and placed side by side at the same horizontal position, so the flaw detection part is This method has the disadvantage that defects near the upper and lower portions cannot be inspected, resulting in uninspectable areas.

る。 That is, in FIG. 5, two probes 10
3a and 103b are brought closest to each other. In this case, the probes 103a, 10
Due to the size of the bottom surface of 3b, it is impossible to align the central axes of the ultrasound sound fields on the transmitting and receiving sides. The distance L between the center axes of the sound field is about 20 mm, and h
The range becomes an untestable area. The height h of this uninspectable area is 1/2 of L, which is about 10 mm. Since this uninspectable area occurs at the upper and lower parts of the welded portion 110, there is a drawback that half of the weld cross section cannot be inspected when the thickness of the inspection member 111 is 40 mm.
