The results of specimen tests show a high sensitivity of the acoustic emission method to the quality of the welded joint. This fact can be used for prediction of the destructive loading and strength limit, which is automatically performed by EMA acoustic-emission diagnostic systems. It is shown how testing of the welded specimens with previously unknown strength parameters can be applied to check the prediction of the destructive loading and the strength limit, which is performed using acoustic emission data. The obtained results indicate that such a prediction is successful and does not require additional adjustment of the predefined system settings. 12 Ref., 2 Tabl., 6 Fig.
