Phased array ultrasonic detection technology of pipe cap weld based on CIVA simulation

In this paper, the phased array ultrasonic testing technology for the welding seam of heat exchange pipe cap of synthetic reactor in a chemical plant is analyzed and studied. The developed special scanning device and wedge are used to perform the test on a contrast block and to optimize the testing technology. The optimized testing technology is verified on the simulation block. The results show that the optimized detection process has a good detection effect, which provides an effective solution for the detection of pipe cap weld.
