文摘

The physical basis of spectral acoustic-impedance defectoscopy is considered. A schematic of the special converter for applying this variant of the method in question is given, and its functionality is analyzed. It is shown that this variant of defectoscopy makes it possible to identify defects, such as starved spots and layer separation, in glued multilayer structures and articles from polymeric composites, which are impossible to identify otherwise.
