PAUT & TOFD in Detail

When safety and precision are non-negotiable, Phased Array Ultrasonic Testing (PAUT) and Time of Flight Diffraction (TOFD) offer unmatched capabilities in non-destructive testing. These advanced ultrasonic methods are widely used in weld inspection, pipeline integrity assessments, and pressure vessel evaluations — especially in industries where traditional NDT methods fall short in accuracy or speed.

PAUT utilizes an array of ultrasonic probes that can electronically steer, focus, and scan the beam, creating detailed cross-sectional images of the tested area. It is ideal for detecting and sizing flaws like cracks, inclusions, and lack of fusion in complex geometries. TOFD, on the other hand, is highly effective for accurate depth measurement of defects using diffracted sound waves, and is particularly suited for detecting planar flaws in thick-walled components.

At 2R Inspection, our certified NDT experts deploy PAUT and TOFD together or independently depending on project requirements, offering fast setup, digital record-keeping, and superior flaw characterization. We follow global standards such as ASME, API, ISO, and EN. Whether it’s for new construction, in-service inspection, or weld qualification, PAUT and TOFD provide powerful insights with minimum disruption. With 2R Inspection, advanced flaw detection is not just a check — it’s a commitment to precision and safety.
