A Clearer Picture: How Phased Array UT Delivers 3-D Results
Today’s advanced phased array UT instruments and software give technicians the computing power to transform traditional 2-D inspection data into full-color 3-D visualizations. Phased array UT software creates a 3-D visualization by layering inspection results, seen in the A-scan data on the left side of the screen, over a CAD file or rendering of the component under test, on the right. The bright “hot spots” indicate corrosion or changes in thickness.
