Quantitative flaw sizing using 3D-CAD ray SAFT

摘要

In sizing defects, tomographic methods such as the Synthetic Aperture Focusing Technique (SAFT) can be used where the time of flight of the received ultrasonic signals plays a more important role than the signal amplitude height. There are two main features of the software, a simulation module, which allows generation of a CAD-drawing of the component to place and automatically scan the search unit, to introduce artificial flaws, and to trace the reflected and mode-converted waves and the reconstruction module based on the principles of SAFT, which allows the generation of 2- and/or 3-dimensional reconstructions on plates, piping, or nozzle-to-shell configurations. For a complex component geometry, the CAD-module can generate the component contour based on measured data and perform data reconstruction by using the actual shape of the real component.
