| 摘要： | The past decade has seen new, emerging innovations in the field of ultrasonic testing (UT). Specifically, multiple manufacturers have been producing phased-array ultrasonic testing (PAUT) systems. The PAUT system embeds a matrix of multiple (some up to 128) single transducers into one probe used for scanning objects. Exciting multiple transducers simultaneously offers distinct advantages; depending on the sequencing of transducer excitation, the ultrasonic beam could be steered within the material, and multiple beams help develop extra-dimensional data to assist with visualization of discontinuity size, shape, and location. Coupled with a linear encoder, PAUT data could also be digitally stored as a permanent record, something not possible for conventional UT. |
