PAUT Inspection
The Phascan supports phased-array inspection using:
Linear scanning
Sectorial scanning
Static scanning
Depth-focused scanning
Multiple focal laws
A-scan display
B-scan display
C-scan display
S-scan display
This makes it suitable for detecting and characterizing internal discontinuities in welds and industrial components.

TOFD Inspection
The system also supports Time of Flight Diffraction (TOFD), allowing inspectors to use diffraction signals for flaw detection and sizing.
PA and TOFD can be used alongside conventional ultrasonic inspection, providing additional flexibility for demanding weld-inspection procedures.
