Surface, near-surface and volume inspection of cast components using complementary NDT approaches

In this contribution we concentrate on the detection and quantitative characterization of casting defects at the surface as well as in the near-surface and the bulk area. For ultrasonic inspection of the bulk material we employ mechanized scanning and defect reconstruction using the Synthetic Aperture Focusing Technique (SAFT). For the near-surface inspection we consider eddy current techniques to identify open or covered defects. Visual surface inspection based on optical systems and image processing complements our multi-sensor approach.
