With the rapid development of machine tools, wind power and other manufacturing equipment industries, the defect analysis and quality evaluation of the application of nondestructive testing methods have become an essential link. At present, widely used and effective detection methods mainly include liquid penetration testing, magnetic particle testing and ultrasonic testing. Liquid penetration testing and magnetic particle testing are often used in defect detection of surface and near surface of castings. Ultrasonic testing is a method for detecting internal defects of castings.
