Quantitative flaw sizing using 3D-CAD ray SAFT

In sizing defects, tomographic methods such as the Synthetic Aperture Focus ing Technique (SAFT) can be used where the time of flight of the received u ltrasonic signals plays a more important role than the signal amplitude hei ght. There are two main features of the software, a simulation module, whic h allows gene-ration of a CAD-drawing of the component to place and automat ically scan the search unit, to introduce artificial flaws, and to trace th e reflected and mode-converted waves and the reconstruction module based on the principles of SAFT, which allows the generation of 2- and/or 3-dimensi onal 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 th e actual shape of the real component.
