Total Focusing Method (TFM)

Total Focusing Method (TFM) is an advanced examination technique that has been incorporated into various codes and standards, gaining increasing adoption across diverse engineering sectors such as aerospace, nuclear, and oil & gas. This method combines traditional Full Matrix Capture (FMC) data acquisition with TFM data reconstruction, offering enhanced resolution and depth of field over a larger area. It also reduces sound wave scattering caused by material noise, which improves both inspection efficiency and performance (ASME Section V, Article 4, 2019 edition). Our TFM training course is specifically designed for advanced inspectors, equipping them with the methodologies and techniques needed to accurately identify and interpret flaws in complex inspections. The course will focus on ultrasonic imaging algorithms that enhance the profiling of indications. Participants will gain proficiency in using TFM processing software to reconstruct multiple paths/modes, enabling effective evaluation and flaw characterization. Topics include flaw dimensioning, display settings, plane wave imaging (PWI), weld and corrosion inspections, and amplitude fidelity.
