Paper Abstract
Modern production processes use more and more components made of new materials like carbon fiber reinforced plastics
(CFRP). These components have different sizes, functionalities, high assembly complexity and high security
requirements. In addition optimized joining processes, especially during welding are implemented in manufacturing
processes. The increasing requirements during the manufacturing of complex products like cars and aircrafts demand
new solutions for the quality assurance. The main focus is to find a measurement strategy that is cost effective, flexible
and adaptive. The extension of the conventional ultrasound technique for non destructive testing with the laser
ultrasound method brings new possibilities into the production processes for example for the inspection of small complex
CFRP-parts like clips and the online observation during seam welding.
In this paper we describe the principle of laser ultrasound, especially the adaptation of a laser ultrasound system to the
requirements of non destructive testing of CFRP-components. An important point is the generation of the ultrasound
wave in the surface of the component under investigation. We will show experimental results of different components
with complex shape and different defects under the surface. In addition we will present our results for the detection of
defects in metals. Because the online inspection of welded seams is of high interest experiments for the investigation of
welded seams are demonstrated.
