Phased Array Ultrasonic
Advanced NDT Phased Array Ultrasonic applications have become almost the norm in many areas of industry today. The benefits of this non-destructive testing technology being the ability to store a full inspection record. The visual display of combined A-Scan, B-Scan, C-Scan and S-Scan gives a simplified understanding of flaw type and associated dimensions.
Phased Array advanced ultrasonic has the advantage over conventional manual ultrasonic NDT techniques because it is possible to inspect large volumes of welds and material from a fixed location. This allows otherwise difficult geometries to be inspected. Thus the technique can be utilized for a very large variation of applications from standard butt welds in vessels and piping to more complex sweepolets, flanges, railway tracks, nozzles, turbine blades and many more.
Example of Phased Array Ultrasonic

Phased Array Technology has also been utilized to perform Ultrasonic examinations for the evaluation of environmental damage mechanisms such as HIC, SOHIC, SCC and HTHA. The sectorial image produced from a phased array scan can often reveal whether stepwise cracking is present between hydrogen blisters that would not be noted from 0 longitudinal inspection. Field trials have determined Phased Array techniques to be the most successful in identifying and sizing Stress Corrosion Cracking (SCC) in stainless steel piping butt welds. The image below indicates typical SCC detected using Phased Array techniques.
