It includes feeding system, flaw detection system and drying system, and completes the flaw detection of parts through a series of operations. The device is designed to use ultrasonic waves to detect pipelines, which greatly improves the accuracy and efficiency of detection. In this paper, ultrasonic nondestructive testing technology is applied to the research of pipeline flaw detection, which has certain practical application value.
