At the ASNT 2025 Conference, Sonatest unveiled its Total Focusing Method with Multiple Modes (TFMI), a groundbreaking advancement in ultrasonic non-destructive testing (NDT). This innovation integrates up to four propagation modes into a single composite image, enhancing the accuracy and reliability of defect detection, especially in complex geometries where traditional methods may fall short. Renato Nogueira, Sonatest’s applications specialist, emphasized that TFMI shifts the evaluation focus from amplitude-based analysis to image interpretation. This approach reduces human error and increases result

NDT uses various analysis techniques to evaluate materials, parts, components, and large structures. The main non-destructive testing methods are: Visual testing (VT), Magnetic particle testing (MT), Magnetic flux leakage testing (MFL), Liquid penetrant testing (PT), Ultrasonic testing (UT), Radiographic testing (RT), Eddy current testing, Acoustic emission testing, Ground penetrating radar (GPR), Guided wave testing, Thermal/infrared testing (IR), Microwave testing (MW), Laser testing (LM), Leak testing (LT). Visual Testing (VT) Visual testing (VT) involves observing the test object’s surface for discontinuities
