Abstract

PURPOSE: To make it possible to separate and detect elastic wave signals from bubble noise and eliminate the influence of electric noise together by using waveguides different in length to detect elastic wave signals at two different points of a solid.
CONSTITUTION: When the constant load tension test in hydrogen addition is performed while generating hydrogen by pouring electrolyte 2 in glass vessel 1 and applying a DC voltage from DC power source 5 to platinum electrode 3 and tested piece 4, waveguides 6 and 7 different in length are provided for the purpose of detecting elastic wave (AE) signals, which are generated at a plastic deformation or destruction time, from different points of tested piece 4, so that AE signals detected by AE sensor 8 may be subjected to signal analysis by channel AE position orientating unit 9. As a result, bubble noise 16 is generated in the position of liquid surface 11 on CRT tube face 10, and electric noise 17 is generated at the center of tube face 10, and AF signal 18 is displayed in a position which is not affected by bubble noise.
