Q. Illustrate process of Radiographic Examination?

Radiographic examination of welded joints shall be performed when required by the Code or additionally when specified in this specification or on equipment data sheets.

The minimum requirement for Code vessels is spot radiography plus the additional requirements of this specification.

Acceptance criteria shall be in accordance.

• UW 51(b) for full radiography

• UW 52(c) for spot radiography

Only lead screens should be used.

All radiographs taken during fabrication shall be available for examination by OWNER.

Where nozzle and manway necks are fabricated from rolled plate the longitudinal seam weld shall be 100% radiographed.

Where spot radiography is required all joint intersections shall be radiographed and one additional spot shall be radiographed in each longitudinal and circumferential seam.

For unfired seam drums, nozzle-to-nozzle weld shall also be radiographed. Fine grain film such as Kodak AA shall be placed to cover the entire periphery of nozzle-to-nozzle attachment weld area. Where radiograph interpretation is questionable, owing to weld configuration, then such areas shall be UT examined.
