Abstract:: Phased array testing technology is a new technology in the field of ultrasonic nondestructive testing. It is a new attempt to apply it to the detection of interface ripple characteristics of explosive welded metal clad plates. This paper introduces the basic principle and technical characteristics of phased array testing technology, analyzes the interface ultrasonic propagation characteristics of explosive welded clad plate and the basic principle of phased array C-scan imaging, and carries out the experimental application research on explosive welded metal clad plate of various materials. It is found that the scanning direction of phased array affects the imaging effect of explosive ripple, it can quickly obtain the explosive wave feature image of the bonding interface of explosive welded clad plate, clearly identify and accurately judge the wave feature, effectively assist the improvement of explosive welded process and improve the product quality of explosive welded clad plate. At the same time, it also realizes a new breakthrough in the evaluation of explosive welded clad quality by non-destructive testing method.
