For many years ultrasonic phased-array techniques have been used successfully in the industry. The Total Focusing Method (TFM) can improve significantly the performances of ultrasonic inspections but for years it has been limited to laboratory applications because of the processing power required to post-process all the data. We have implemented this technique in real-time on a portable unit allowing to use this technique on the field. In this paper, we’ll present the application of the TFM method to the inspection of samples containing hydrogen damages (HIC and HTHA) and compare it to traditional phased-array inspections. We’ll also look at other industrial cases to show the advantages of the TFM.
