PAUT, TOFD & TFM Inspection
Advanced ultrasonic techniques with imaging, sizing and recorded data.
The inspection problem
Manual UT is fast but leaves the inspection decision entirely on the operator. PAUT, TOFD and TFM give imaged, recorded, reviewable results — provided the system, wedge and procedure are matched to the weld.
Why it matters
Recorded imaging turns UT into an auditable inspection: better defect discrimination, better sizing, defensible data.
Which method fits your part?
Every method has a sweet spot and a limitation. Choose based on defect, geometry, throughput and access — not on habit.
PAUT
When it fits: Weld inspection, complex geometries, imaging and sizing.
Limitations: Requires calibration blocks and skilled operators.
TOFD
When it fits: Fast weld coverage, height sizing of embedded flaws.
Limitations: Dead zones near the surface and back-wall.
TFM
When it fits: High-resolution imaging with full matrix capture.
Limitations: Data volume and processing considerations.
