Intermodal Total Focusing Method (TFMi™) and Multi-technique Ultrasonic Sizing Analysis Study

Since its launch in 2021, TFMi™ has introduced intermodal imaging results shared throughout the PA-UT sector. This recent technique opens the door to high geometric fidelity imaging.

The primary objective of this research paper is to investigate the Phased Array Ultrasonic
testing performance metrics among many welds that have been recorded with a Sectorial-scan (S-scan), a TFM, a TFMi™ and a TOFD. The main 3 metrics are height precision, detection rate and characterisation success.

Each technique should have pros and cons to discuss. Because of the longer legacy of the ultrasound, our contestant will have more experience with S-scan and TOFD data than other groups. There is a high level of human factors influencing an inspection, but the goal of the study focuses on the post-analysis part. It should demonstrate a difference of performance through the competitors. In addition to that, we also request specialists to use the same rejection criteria.
