丁老师,关于ASME标准中根部内凹的评定,给点意见,怎么处理,按什么评定呢?
摘自ASME-III NE-5000 c) internal root weld conditions are acceptable when the density change or image brightness difference as indicated in the radiograph is not abrupt; elongated indications on the radiograph at either edge of such conditions shall be unacceptable, as provided in (b) above; ( (b) 条状缺陷评定规定)
上面怎么理解,如果对管道类环形焊缝,难道没有影像突变的内凹就按照条形缺陷评定?
