Conventional TOFD struggles with high-temperature inspections due to transducer limitations and signal interference. In this case, Ionix high-temperature TOFD transducers with integrated wedges enabled reliable inspection of a carbon steel pipe weld at 200 °C. Mounted on a modified EddyFi Lyncs scanner and paired with a Mantis UT system, the setup successfully identified weld root corrosion, demonstrating suitability for continuous operation up to 350 °C.

Wright Quality Services (WQS), a leading Canadian NDT service provider, conducted routine maintenance inspections on a high-pressure steam line for a refinery operator. Utilizing advanced Phased Array Ultrasonic Testing (PAUT) and high-temperature Time of Flight Diffraction (TOFD) methods, WQS effectively detected weld root erosion under extreme conditions exceeding 300 °C. The inspection, focused on identifying early signs of deterioration, provided high-resolution imaging and superior accuracy, ensuring the reliability of critical welds in high-pressure steam systems.
