PA UT (PAUT): Butt Welds - Planar and Circumferential

ISONIC EXPERT software application was created for the inspection of planar and circumferential butt welds with symmetrical bevel, and the like with use of wedged linear array probes situated either on the parent material or on the machined weld cap

The movie below illustrates the inspection of the planar butt weld with use of the ISONIC 3510 instrument

The movie below illustrates the use of ISONIC 2010 instrument and the bracelet scanner whilst scanning the reference block for the inspection of circumferential butt welds in the small OD boiler tubes

The movie below illustrates the results of scanning of the Z-Cut ASTM E-1961 calibration block for the inspection of girth welds; the block contains reference reflectors (flat bottom holes and notches) at various locations. The pure S-Scan, the EquPAS S-Scan coverage and imaging were aplied along with the TFM sparpening of the pure S-Scan data:
