High-Temp TOFDs
The High-Temperature TOFD transducer acts like a conventional TOFD transducer but designed for temperatures up to 200°C (392°F). Time-of-flight diffraction is a method used to determine the size of mid-wall and I.D. cracks in metallic welds. It requires highly-damped, broadband transducers and wedges that generate refracted longitudinal (L) waves. The high-temp TOFD transducers come standard with a straight-mounted Microdot connector. The TOFD wedge is also designed for use up to 200°C (392°F) and includes two coupling irrigation ports and gimbal-mounting holes.
Temperature & Testing Data
This data is calculated with the transducer, wedge, and asset all at 150°C (peek data) or 200°C (celazole data). During actual inspections, there will be a temperature gradient from the asset up to the transducer.
