Webb16 dec. 2024 · The difference between PAUT and TOFD lies in the response of the physical principle (ultrasound) that produces any discontinuity in the material. PAUT is based on the reflection of ultrasound waves, while TOFD is based on the response of diffracted waves indicating the tip. This difference is an essential factor in assessing indications that ... WebbTOFD examinations can be performed at temperatures in excess of 400ºC on finalized welds. Partly-welded thick sections can be examined at pre-heat temperatures to avoid costly root repairs from the outside surface after welding is complete. TOFD data is extremely accurate and presented in an easy-to-understand format. sculptures in borrego springs
