PA UT (PAUT): Corner (L-Shape) Welds
ISONIC EXPERT CORNER CU software application was created for the inspection of curved profile Corner, Nozzle, L-Shape welds, and the like and the adjacent material with use of wedged linear array probes situated on the curved flange surface
ISONIC EXPERT EDGE software application was created for the inspection of Open Corner and Edge joints and the adjacent material with use of wedged linear array probes situated on the outer surface of the suitable member

The video below illustrates practical inspection of nozzle weld:
The video below illustrates detection of the crack in the corner weld between thin wall aluminum members:
The video below illustrates the typical indications obtained on the screen of ISONIC 2009 instrument whilst inspecting tube-to-tube welds using CORNER application:
Three videos below illustrate the inspection of the corner welds on the tubular shafts using the CORNER (cricumferential) and CORNER CU (longitudinal) application running in the ISONIC 3510 instrument:
Besides testing of the corner welds ISONIC EXPERT CORNER and CORNER CU inspection software applications are well suitable for a wide variety of other inspection tasks. One of them relates to the detection and sizing of the Flow Accelerated Corrosion (FAC) on the ID surface of the tubes and vessels near the access holes sealed by radiographic plugs:
Some more details about the FCA detection and evaluation is available on the pages 19 through 22 of the

The videos below illustrate the ability of ISONIC series PA instruments of on-the-fly toggling between live True-to-geometry (True-to-Shape) and FMC/TFM coverage and imaging for the straight and curved profile welds
Also the toggling between True-to-geometry (True-to-Shape) and FMC/TFMhe images may be performed off-line at the postprocessing stage - such ability has been provided thanks to 100% raw data capturing when the primary A-Scans for each element of the receiving aperture are stored for each implemented focal law:
Inspection of the open corner welds using the ISONIC EXPERT EDGE application is presented by the video below
