Abstract

The verification of kissing bond defects with conventional nondestructive testing techniques is generally unsuccessful because kissing bonds behave very similar to an intact adhesive. Therefore, one has to apply a suitable method such as loading the adhesive joint using laser-generated shock waves in order to make this kind of defect detectable. The present work describes the results of experimental studies on nondestructive inspection of bond flaws in bonded joints of metal materials. While it is not the purpose of this work to evaluate or characterize shock waves, we demonstrate that kissing bond flaws can be made visible nondestructively using laser generated shock waves.
