Investigations performed to study the strength behaviour supply informations about the failure pattern under loading. Beside metallographic and fractographic investigations acoustic emission measurements are used for interpretation. The results obtained for brazed joints – Ni Cr 20 Ti Al/BNi‐5‐ show by means of the analyzed acoustic signals the possibility to evaluate the quality of a joint after a short loading period. Furthermore, hints were given to reduce the testing expenditure being necessary until now by the application of the acoustic emission analysis remarkably.
