Adhesive joining is a method that gains ground within primarily the automotive segment due to the introduction of light weight materials and difficult material combinations. Light weight metals like aluminium, titanium and magnesium along side of polymer matrix composites has been used within the aerospace industry for quite some time, but the production series within the automotive segment is usually significantly longer and the production time usually more limited To be able to work with quality assurance on a continuous basis demands non destructive evaluation methods that are fast, reliable and preferably possible to at least partly automate. There are several non destructive evaluations methods that might meet these demands, e.g. (computerised) visual inspection, shearography, IR thermo-graphy, acoustic emission, computer aided tap testing and a few ultrasonic techniques: Guided Wave inspection and laser ultrasonics. In many cases it is desirable to evaluate a bondline prior to adhesive setting, but due to the basic principles of the evaluations method, the adherends or a combination thereof, this is not always possible. In some cases, however it is possible with considerable potential cost saves as a result. The NDE methods probably best suited for pre setting evaluation is IR thermography and Guided Wave inspection. In some cases visual inspection, possibly computer aided, can be a feasible alternative as well.
