Design of Automatic Ultrasonic Inspection System of Longitudinal Welded Pipe

Aiming at the problem of low manual detection efficiency and high failure rate in traditional longitudinal welded pipe production, using the advantages of high accuracy, high speed of ultrasonic nondestructive testing, taking the programmable controller(PLC)as the core, a set of automatic ultrasonic inspection system of the longitudinal welded pipe is designed. The paper summarizes the longitudinal-seam welded pipe automatic ultrasonic inspection system. The process parameters and the mechanical structure of the system are put forward, and the PLC control hardware, program flow and control procedures of the system are designed accordingly. A touch screen is chosen for system operation monitoring, and the man-machine operation monitoring picture based on the touch screen programming software design of the Windows system is given.
