Abstract:
The basic principle of TOFD (time of flight diffraction) technique as a new non-destructive test (NDT) method is introduced in this paper. Based on the application of this technique, TOFD standards, reference blocks, sensitivity adjustment and analysis of testing results are discussed. It may be helpful for popularizing this technique in China.[著者文摘]
