The Contrast of Defect Tested by PAUT and RT

This passage introduces several imaging ways in phased array testing. We choose simulated defect test plate to detect. The images of familiar harmful defects in weld such as crack, layer incomplete fusion as obtained by phased array and radiograph were contrasted and analyzed. Image characteristics of several defects tested by different technology were indicated and the identification of defect properties in PAUT was preliminarily studied and the superiority of the technology was described.
