Within the framework of quality monitoring of lightweight construction components intelligent sensor systems become crucial: In many industries, especially in aerospace engineering and automotive industry, the use of forward-looking hybrid designs based on fiber composites and light metals is steadily rising. Material defects in the final product may result in early malfunction, thus, impairing the safe use of the product. From 25-29 June 2019, at the 14th International Foundry Trade Fair in Düsseldorf, Fraunhofer IZFP scientists will introduce a robot-assisted sensor system for the nondestructive inspection of hybrid cast components, which can easily be integrated into the quality monitoring of production processes (hall 13, booth A34).

Time-consuming destructive inspection methods used in quality assurance result in enormous costs, as the product is damaged or even destroyed during the process. Moreover, as a consequence of destructive inspections being randomized, process disturbances are often not detected until a considerable amount of scrap has already been produced. Thus, nondestructive methods offer an alternative and, after adequate realization, even a long-term substitute for destructive methods. The Fraunhofer Institute for Nondestructive Testing IZFP in Saarbrücken inspects components or parts already during the manufacturing process, without damaging the material itself or changing the surface and properties.
Cognitive sensor systems for inline quality monitoring of production processes
The benefits of robot-based inspection with eddy current compared to conventional computed tomography relate to the uncomplicated inspection with significantly less necessary safety precautions as well as to the assessment of relevant quality features: This preserves resources, reduces costs and helps to strengthen the competitive position of producers. This Saarland research institute is endued with decades of experience and know-how in the field of combination and automatization of nondestructive inspection methods for production lines.
Cognitive sensor systems – efficient processes
In addition to pure production processes, the activities cover equally processes from materials and product development, maintenance, repair, and recycling of materials.
