Abstract
This paper considers the physical bases of the ultrasound reverberation method that can detect defects in gluing of double-layer structures made of dissimilar materials, such as metal–plastic and plastic–metal. The advantages and disadvantages of this method are specified. It is shown that the capabilities of the reverberation method significantly expand when using a spectral version of reverberation based on registration of changes in the shape of the envelope of the amplitude spectrum of echo pulses depending on the quality of bonding.
