| Abstract: | In view of the flat butt welds in ship construction, the steel base materials of different thicknesses are used to make a comparison of equivalence requirements of testing technology standards and conduct a testing equivalence test between Digital Radiography Testing (DRT) and conventional film Radiography Testing (RT), and DRT and conventional film RT of weld defects of test plate are evaluated. The results show that DRT and conventional film RT are of equivalence. |
