New Concepts for Quality Assurance of Lightweight Material

Abstract Lightweight material became more and more important during the last years. To ensure a defect-free production, effective measurement solutions for quality assurance are necessary. The Laser stripe sensors enable the evaluation of form deviations. For the detection of internal defects thermography provides a suitable solution. On this account the combination of these two non-destructive testing principles gives an opportunity to detect different kinds of defects regarding the outer geometry and the material within the parts. This paper deals with varied concepts to combine laser stripe sensor system and thermography and shows the potential of these methods.
