Ionix high-temperature TOFD transducers, with integrated wedges, are suitable for weld inspections at continuous elevated temperatures up to 350 °C. Here, the transducers with integrated wedges are mounted on to a modified EddyFi Lyncs scanner for high-temperature encoding, with high-temperature couplant, connected to
commercially available Mantis UT set, and a carbon steel pipe weld inspected at 200 °C for weld root corrosion.
Ultrasonic time-of-flight diffraction (TOFD) is a popular method widely used in petrochemical, energy and other industries for the in-service detection and characterisation of welds defects such as root corrosion, porosity, inclusions, and cracks. This latest application note explores Time-of-flight diffraction on carbon steel welded plate up to 240 °C.
A demonstration of the Ionix high-temperature TOFD transducers, with integrated wedges, for their suitability for weld inspection at elevated temperatures up to 240 °C is shown here. The wedges are mounted on to a modified EddyFi Lyncs scanner for high-temperature
encoding, with high-temperature couplant, connected to commercially available UT sets from EddyFi and
Olympus.

Here, the transducers with integrated wedges are mounted on to a modified EddyFi Lyncs scanner for high-temperature encoding, with high-temperature couplant, connected to commercially

Ultrasonic time-of-flight diffraction (TOFD) is a popular method widely used in petrochemical, energy and other industries for the in-service detection and characterisation of welds defects such as root corrosion, porosity, inclusions, and cracks. However, with increasing demand for on-stream measurements, conventional TOFD is limited due to the temperature at which these probes can operate, often causing failure of the transducer, or causing noise in the wedges to mask the ultrasound signal.
