、超音波の送受信の安定性が損なわれてしまう。However, manual application work is extremely troublesome and inefficient. In particular, when performing flaw detection on an upper part of a ceiling or the like, a viscous medium such as grease must be used to prevent the medium from dripping, making the application process difficult and further deteriorating the flaw detection efficiency. Furthermore, if uneven coating occurs, the stability of ultrasonic transmission and reception will be impaired.

よい。The shape of the probe adapter QO is not limited to the illustrated example, but in short, the probe adapter QO is a medium storage where a probe is attached, the top is open so as not to interfere with ultrasonic transmission and reception of the probe, and an appropriate amount of medium can be stored. and a recovery chamber that receives the medium overflowing from the upper edge of the storage chamber, and is grounded so that the probe is oriented perpendicular to the flaw detection surface of the object to be tested. It is something. In addition, in order to facilitate the application of the medium to the flaw detection surface during scanning operations, the height of the zenith surface of the chamber wall (1]) forming the medium storage chamber is adjusted to the height of the outer chamber that is grounded to the flaw detection surface as shown in the figure. It is desirable that it be slightly lower than the wall @. The difference in height (cl) [: the gap between the flaw detection surface and the chamber wall αυ zenith surface] depends on the roughness of the flaw detection surface and the viscosity of the medium, but the height difference (cl) [: the gap between the flaw detection surface and the chamber wall αυ zenith surface] depends on the roughness of the flaw detection surface, the viscosity of the medium, etc. A few millimeters is sufficient.

If necessary, several similar grounding members αa may be installed on the top of the storage chamber walls.The zenith surface of each chamber wall αH2 is normally a flat surface, but , to stabilize the grounding,
The probe can be shaped to suit the surface shape of the object being tested (for example, a curved surface such as a tube body), and the probe can be detachably attached to the storage chamber (A) so that the adapter can be replaced at any time if desired. May be made to be mounted.

を行なうことができる点で好ましい。The vertical position of the probe (1) within the storage chamber (5) may be determined as appropriate. Of course, the front end surface of the probe may be placed close to the flaw detection surface as in the direct contact flaw detection method, but if it is set back from the flaw detection surface and positioned at an appropriate distance as shown in the figure, so-called local This method is preferable because stable transmission and reception similar to immersion testing can be performed.

容器０υ内に補充するようにしてもよい。In the medium recycling circuit, in order to remove impurities (such as rust attached to the surface of the object to be inspected) mixed into the medium recovered from the adapter 00, the medium container 0 is removed, for example, as shown in the figure. ) A strainer (g) may be attached to the tip of the suction pipe (c) to separate it from the circulating flow of the medium. In addition, this recycling circuit directly transfers the medium drawn out from the recovery chamber (G) of the adapter to the medium container (G).
Instead of returning the waste to the 3D, it may be temporarily collected and stored in a container other than the medium container, and after the foreign matter is removed from the furnace, it may be replenished into the medium container 0υ.

In particular, the probe in the medium storage chamber is not brought into direct contact with the flaw detection surface.
If a medium is interposed between the flaw detection surface and the flaw detection surface, the transmission and reception of ultrasonic waves can be made more stable as a local immersion flaw detection method, making it suitable for automatic flaw detection.
