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. (Photo: Zetec)

Essentially, the process involves merging data from 2-D scans taken from different positions and angles and overlaying it onto a CAD file or 3-D rendering of the pipe, joint, weld or other type of specimen that’s under test.

Software packages like Zetec’s UltraVision can also simulate acoustic beams and characterize the energy distribution from any given probe, including single-element (conventional UT), 1-D-linear arrays and 2-D-matrix arrays.

These renderings are so clear and detailed that you don’t need a deep understanding of UT scans to easily recognize corrosion, weld defects and other indications on the screen. 

Having a clean, easy-to-interpret picture on the screen, in a moment, lets inspectors and clients alike clearly see the condition of their assets to help inform their decisions about safety, uptime and code compliance.
