Development of automated non-destructive evaluation (NDE) systems for reinforced concrete structures and other applications

The introduction of an innovative process for non-destructive testing is described in term of its different phases and how the process is controlled in the Fraunhofer IZFP in order to obtain optimal results. Examples are discussed of applications by IZFP in various important and safety-relevant industrial sectors where the automated inspection systems were introduced. These case studies include the inspection of railway components such as the wheel sets of the German high-speed train and in-line pipe inspection by using intelligent pipeline inspection gauges. Complex inspection systems, both hardware and software, developed in partnership with the Federal Institute for Materials Research and Inspection (BAM), were applied to inspection tasks in civil engineering. Two automated systems based on a robot and on a flexible manipulation are presented. Both systems can be applied to diverse inspection technologies and to the data fusion of various types of non-destructive testing (NDT) data.
