Re: Ultrasonic PHASED ARRAY Technology Xavier -
I am happy to hear of the growing interest in the Phased Array technology.
I work for NASA, at the Marshall Space Flight Center. We have a R/D Tech Tomoview system with one transducer: 64 element array, 10Mhz.
We are developing the inspection techniques for use on Friction-Stir welds of the External Tank. This will eventually be used in production -- probably a crawler type bridge, with dual 64 element, or maybe dual 128 element, transducers. Vertical inspection.
There seemed to be a large initial learning curve for Phased Array inspection, but we now are very confident in this method. We are detection LOP @ 0.020" and above, with detection of LOF as well.
Sensitivity, detection, mapping - all seem to surpass any other NDT method we have currently. RT, PT, ET, nothing comes close to the data the Phased Array unit gives.
I would like to keep informed of others who are using this method. As you mentioned, presently, we are in a "lab" environment, but soon will move to the production floor on full scale External Tanks.
In the lab, we have plates of 0.320" & 0.650", but now are able to inspect tapered plates of 0.650-0.320 just fine.
Thanks for the post.

Re: Ultrasonic PHASED ARRAY Technology : Xavier -
At present we are using the R/D Tech PipeWIZARD system to inspect pipeline girth welds.
I would be interested in receiving any information you have about Phased Array inspection.
Exertus Dual 120
The Exertus Dual 120 Projector has the ability to accept Iridium 192
sources or Selenium 75 source
s. This projector incorporates design
safety features that make it flexible, compact and lightweight.
The Projector is lighter than most of its competitors. It
incorporates an improved source channel, based on a new helicoidal
design, which makes maintenance easier. The helicoidal design also
allows smoother movement of the source assembly inside the device,
making it easier for the operator and improving safety. The
Projector also has a unique safety feature not found in competitive
The source assembly locking mechanism is triggered by the source
holder capsule at the front of the source assembly, thereby always
assuring the operator that the source has returned to the
safe position. The Exertus Dual 120 is ISO3999:2004 compliant.
