PA UT (PAUT): Tandem B-Scan
ISONIC 2009 UPA Scope and ISONIC 3510 instruments are featured with the ability of performing ISO 16826:2012 compliant Tandem-B-Scan cross-sectional coverage and imaging technique providing the rapid reliable detection of the vertical and close to vertical planar defects in the welds, plates, tubes and vessels walls, rails, and the like is provided. 64-elements wedged linear array probe is required for that purpose. It should be connected to the instrument's PA probe terminal either directly (ISONIC 2009 UPA Scope)
or through S 4922A064D016 active PA functionality extension adapter (ISONIC 3510)
The video below illustrates the principles of forming focal laws and providing Tandem B-Scan screening of the material:
The instruments allow composing and implementing a group of tandem focal laws a strip chart - this mode of operation allows quick line-scanning of the narrow gap welds with zonal discrimination, butt welds in HDPE pipes, etc as it is illustrated by the videos below:
