The explosive welded titanium/steel clad plate is used in a chemical project in China. In addition to the bonding performance higher than the standard requirements,the uniformity of interface bonding is also required. At present,the common ultrasonic pulse echo method is difficult to determine the uniformity of interface bonding,and the conventional ultrasonic C-scan detection speed is slow,which can not meet the requirements of mass production schedule. The phased array technology is applied to the detection and acceptance of explosive welded laminated metal clad plate products in China. Phased array detection greatly improves the detection efficiency through electronic scanning. At the same time,combined with the C-scan image,it makes the identification and judgment analysis of interface wave of explosive welded titanium/steel clad plate clear and intuitive,and has a certain corresponding relationship with the bonding performance.
