·

If there are defects such as voids in the structure or panel, it can be checked whether it is destroyed or not. However, this destructive inspection is not suitable for all products because there is a lot of waste. In order to investigate cavities in welds and castings, it is necessary to conduct ultrasonic inspection or eddy current tests to examine the scars and internal defects of X-ray, γ-ray and β-ray transmissions, steel plates, forgings, , Infiltration method (magnetic permeation method) or magnetic particle detection method (magnetic particle flaw detection method) is used for finding a small wound on the article surface.

The double ultrasonic inspection method (ultrasonic wave inspection method) is a method using the principle of taping. The ultrasonic wave from the oscillator is inserted from one side of the article to receive the reflected wave from the other side. When there is a defect inside, the wave reflected from the defect returns. This is the same as if a railway line worker knocks the machinery or axle of the undercarriage with the sledgehammer and finds defects in that part. The eddy currents are found by deflecting currents flowing through eddy currents in articles by means of high frequency induction.

The above ultrasonic inspection method is also used for inspection of foreign matter, cracks, etc. inside the panel even when the panel of an aircraft structure is manufactured.

1 is a schematic view of an ultrasonic inspection apparatus for a conventional panel. The ultrasonic inspection apparatus 10 includes an ultrasonic transmitter 11 disposed on one side of a panel P and an ultrasonic receiver 12 disposed opposite to the ultrasonic transmitter 11 on the other side of the panel P . At this time, the ultrasonic inspection apparatus 10 moves along the plane direction of the panel P to grasp the abnormality of the panel P, and the ultrasonic waves irradiated from the ultrasonic transmitter 11 during the movement are detected in the plane direction The ultrasonic wave is transmitted to the ultrasonic receiver 12 without error so that the panel P can be precisely detected.

At this time, in the case of the flat panel of the panel P, even if the ultrasonic inspection apparatus 10 moves along the plane direction of the panel P, the ultrasonic waves are always irradiated perpendicularly to the plane direction of the panel P. However, P is bent, the displacement of the ultrasonic inspection apparatus 10 needs to be corrected in real time in order to irradiate the ultrasonic wave perpendicularly to the plane direction of the panel P. However, it is practically impossible to inspect only a part of the panel P A problem arises in that the remaining parts of the panel must be manually inspected for the abnormality of the panel through a separate ultrasonic inspection apparatus.
