Abstract:

Growing incorporation of adhesive joints in automotive body production routinely demands development of fast and reliable non-destructive testing methods. The structural geometry of ‘metal sheet - structural adhesive - metal sheet’ makes it complicated to use the convenient pulse-echo ultrasonic technique. A few algorithms of received signal processing were proposed for elimination of reverberation oscillations, detecting and interpretation of the informative signals. These methods, based on adaptive filtration and correlation analysis, were realised for scanning acoustical microscope data obtained in experiments with epoxy-based polymer adhesive samples. Their advantages and effectiveness were demonstrated and compared. Limitations of these techniques are also discussed. Results of data processing of the acoustical images for basic types of defects (voids, delaminations, uncured regions) are represented and discussed.
