Title: RADIOGRAPHIC EXAMINATION PROCEDURE FOR BUTT WELDS
General
This procedure is applied to the x-ray radiographic examination of butt welds for pressure vessels constructed in accordance with ASME Code Section Ⅷ Div1.
This procedure shall be supplemented, when necessary, with the examination instructions defining more specific variables, which will be prepared by NDE Level Ⅲ personnel.
2. Qualification of Examination Personnel
Any person engaged in the radiographic examination shall be qualified and certified as a radiographic examiner in accordance with NJBST Co., Ltd.’s “Written Practice for NDE Personnel Training, Examination, Qualification and Certification”(NO.: QCD-011).
The NDE LevelⅠshall receive the necessary instruction or supervision from a certified NDE LevelⅡ or LevelⅢ Examiner. The NDE LevelⅡ shall receive the instruction or supervision from a NDE Level Ⅲ Examiner.
According to the respective responsibility range, all examiners plete the examination conforming to the referencing ASME Code Sections, standards and written instructions. They shall assure the working quality.
3. Equipment , Tools and Materials
