2013的注解c中明文规定UT可以取代RT，而且在这种情况下可以免去弯曲试验BENT TEST。无论新旧版本只做RT的话，都是不能免去弯曲试验BENT TEST的，为什么呢?有解释，是因为这种焊接型式(131、135、138和311)容易产生FUSION TYPE DEFECT（熔合性缺陷），例如：CLD LAP（冷焊）。射线检测RT是不能有效检测出来的。
2008年5月我们在为一批10个焊工考试时做了RT和BENT TEST,RT全部合格,10个焊工却只能有3个能通过弯曲试验。 这就说明焊工很难操作,而射线却很容易漏检。 焊工考核的详细资料如下: Welding process:(135) MAG welding Product Type:(P) Plate Type of Weld:(BW) Butt Weld Material Group:W01 Welding Consumable...
