Ultrasound Inspection

Time-of-Flight Diffraction Testing

$Time of Flight Diffraction Testing with OmniScan$

Time-of-flight diffraction (TOFD) is a technique that uses two probes in pitch-catch mode. TOFD detects and records signals diffracted from defect tips allowing both detection and sizing. The TOFD data is displayed in a grayscale B-scan view. TOFD offers wide coverage and amplitude-independent sizing complying with the ASME‑2235 code.

One-line scan for full-volume inspection
Setup independent of weld configuration
Very sensitive to all kinds of defects and unaffected by defect orientation

TOFD and Pulse-Echo Testing

Time of Flight and Pulse-Echo diagram

While TOFD is a very powerful and efficient technique, its coverage is limited as a result of two inspection dead zones: one dead zone is near the surface, the other is at the backwall.

The OmniScan® UT allows inspections that simultaneously combine TOFD with conventional pulse echo. Pulse echo complements TOFD, covering the dead zones.

TOFD inspection
45º pulse echo for weld cap inspection on either side of the weld
60º pulse echo for weld root inspection on either side of the weld

0‑Degree Testing (Corrosion and Composite)

0-degree testing measures the time-of-flight and amplitude of ultrasonic echoes reflecting from the part into gates in order to detect and measure defects.
