PURPOSE:To facilitate the evaluation and inspection of the quality of a joint surface by connecting an amplifier to a detector for elastic wave through a wire code after it is mounted on a load for applying a direct load on a sample fitting. CONSTITUTION:In this apparatus, a detector 15 for an elastic wave is mounted on a load body 14 for applying a direct load on a sample fitting 13, an amplifier 17 connected the detector 15 through a wire code 16 and a waveform processor 21 connected the amplifier 17 through a wire code 20. Then, all elastic waves including noises are caught and processed with the waveform processor 21 to evaluate. In this enbodiment, the quality of adhesion between the rubber of a rubber roller and a fitting can be inspected totally in a non-destruction manner without misjudgement. |
