Study on Control System of Scan Robot for Circumferential Weld

Abstract:

As the detection efficiency and defect evaluation accuracy of traditional ultrasonic testing of weld is low, in this paper a new control system is developed to accomplish high-efficiency and high-precision evaluation of weld. This system includes Centralized Control, Control of ultrasonic probe and running mechanism. The heart of the system is DSP, and it can control motion of the scan robot along the circular rail and ultrasonic probe along radial direction of circumferential weld, and realize collection and processing of ultrasonic signal by the comprehensive application of computer, automation, precision instrument, motor driver technology. Practice shows that this new system has realized digital, intelligent, automation of ultrasonic weld inspection, and improved Reliability and efficiency of weld inspection.
