The total focusing method (TFM) is suitable for ultrasonic inspection of components across a range of different industries. When using the TFM however, the quality of results depends greatly on the setup used. Selecting the most suitable scan plan increases probability of detection, and the use of intelligent modelling tools during setup both saves time and increases chances of success.
In nondestructive testing, the TFM is a way to improve the detection capabilities of linear pulse-echo probes. It does this by using all the available probe elements to focus the beam electronically in all points of a given region of interest. The technique may in some cases improve detection sensitivity and resolution inside a predefined area.
