Abstract: This paper introduced the working principle of the TOFD equipment and two depth calibration methods of single-channel TOFD equipment, i.e. lateral wave calibration, lateral wave and back wall echo calibration. Derivation of the two calibration methods, the advantages and disadvantages of various calibration methods and the scope of application of each calibration method were discussed.
