Journal of Nondestructive EvaluationCONG Sen, GANG Tie, ZHANG Jiaying. Ultrasonic time-of-flight diffraction testing with linear frequency modulated excitation for austenitic stainless steel welds[J]. Journal of Nondestructive Evaluation. 2015, 34(2):8-18....
ToFD is an innovation of ultrasonic testing which uses two probes. One probe sends the ultrasound and the other one is used as a receiver. Instead of recording the ultrasound that is reflected by defects, it detects diffraction of sound waves that emanate from the tips of a defect. ToFD ins...
Intertek offers a comprehensive range of non-destructive testing methods. Therefore we can provide the other methods used to complement time of flight diffraction such as phased array, in particular to perform single sided examinations of welds. ...
