Abstract

The possibility of detecting specific structural defects in dissimilar welded joints—carbide and decarburized ferrite interlayers—by the acoustic emission (AE) method is investigated. These interlayers are formed in dissimilar welded joints of austenitic and pearlitic steels during welding and subsequent operation.
