Abstract
Aiming at existing boundedness of conventional ultrasonic testing method in testing 3D changeable cross-section runner weld,this paper introduces features of phased array ultrasonic testing technology.According to defect types easy to appear of runner weld,it makes simulation samples and designs ultrasonic phased array testing technology to test detected de-fects and proceed conventional ultrasonic testing verification.The result indicates that ultrasonic phased array technology is obviously able to improve testing effectiveness and detecting ability but it is not able to finish fuse of interlamination of bad exposure.Thus,it is necessary to carry out supplementary testing on the weld cambered surface by coordinating with normal probe.关键词
