Easy-to-handle non-destructive testing methods for components are getting more and more important to achieve “zero failure production”. Especially in the aerospace industry, the responsible quality managers have to follow a strict 200% testing-approach. This means, a full-faced checking of the part is performed by an automated NDT system as the first step of the procedure. Areas that show deviations from the reference dataset are marked as so-called „findings“. In a second step a qualified auditor needs to evaluate these findings on a PC-monitor as „ok“, „defect“ or „ignore“. Finally, these rated findings are required to be again validated by manual NDT measurements on the real component.
This rather unintuitive workflow requires a change of the perspective between the graphically illustrated dataset on a monitor and the real component, which is not only a further source of errors but also leads to focusing on the defective areas only. With the advancement in headsets, cameras, and tracking technology, augmented reality is gaining more and more traction. Augmented reality extends the physical world with digital assets, such as static or animated overlays.
In this paper we will show the actual status of the project Aurea NDT dealing with a new way of showing NDT results by augmented reality in combination with the NDT method “Laser Ultrasonics”. By expanding the perception of the real environment (component under test) with additional information provided by the NDT measurements an intuitive way of working and interpreting the results is possible. For example, color-coded thickness values are displayed directly on the surface of the real component to give a very intuitive impression of the component’s shape or to show defects.
