Study on Ultrasonic Automatic Detection System of Large Steel Plate

With a large number of applications of large steel plate, in order to ensure the engineering and product quality, it is necessary to test the quality of large plate. In the domestic, large steel is detected mainly by hand, there are some defects such as low efficiency, large strength, easy to misjudge and leakage judgment. This paper presents an ultrasonic automatic detection system design of large steel plate, multi-channel tests steel plate, stepper motor controls motion, Ethernet transmits data; Designing the system circuit, giving probe scanning method, defects determination method and selection and arrangement of probes. The system has high detection efficiency and high precision, simple mechanical structure, small size, low cost, and has an important application. (C) 2011 Published by Elsevier Ltd.
