Ultrasonic testing - Ultrasonic testing
|
This is a non-destructive inspection that uses ultrasound to detect defects in metal materials, etc. When ultrasound passes through an object, some of it is reflected back in the direction of incidence when it encounters a defective part, and the transmitted energy is attenuated. The strength of the reflected and transmitted waves can be used to determine the presence, size, and properties of defects. The frequency of the ultrasound used is 0.5 to 10 MHz. → Related topic: Ultrasound Source : Heibonsha Encyclopedia About MyPedia Information |

超音波を利用して金属材料などの欠陥を検出する非破壊検査。超音波が物体内部を通過する際，欠陥部分に突き当たると一部は入射方向に反射し，透過エネルギーが減衰することから，反射および透過波の強弱により，欠陥の有無，大きさ，性状などを知る。使用する超音波の周波数は0.5〜10MHz。 →関連項目超音波 出典 株式会社平凡社百科事典マイペディアについて 情報 |
