| Abstract: | There are a large number of welded joints in port hoisting machinery structure,and the inspection requirements are high. The diffraction time difference ultrasonic inspection (TOFD) is an effective means to improve the inspection quality. According to NB/T 47013.10 standard，the paper introduces the main technical steps and process methods of testing butt welds of port crane by TOFD method. At the same time, it can provide reference for TOFD testing of other types of products or equipment. |
