ACOUSTIC EMISSION DETECTION OF FLAWS IN BUTT-WELDED PLATES

Acoustic emissions were monitored during mild flexural deformation of butt-welded steel plates after cooling of the welds. Measurement of the difference in the arrival times at two transducers was used to locate predominant sources. These were then compared with the location of known flaws. This study demonstrates the feasibibility of employing acoustic emission monitoring as a method of evaluating the quality of welds. Requiements, which are appropriate to quality control on an assembly line, are discussed.
