Acceptance of Internal Reinforcement using Radiography

  • Acceptance of Internal Reinforcement using Radiography

    Dear Forum,

    As per the subject data field:

    If a component is not accessible to perform a visual assessment of the internal reinforcement (root protrusion) and radiography is executed to determine the final weld integrity: how does one go about when the referencing code section, B31.3, specifies that the flaw can only be cause for acceptance or rejection based on a visual assessment, but it is evident on the radiograph that the internal reinforcement is excessive:

    (1) Density variation
    (2) Thickness gaging across the respective surface area, provided the crown is dressed

    B31.3 isn’t clear on how to approach this scenario and doesn’t give guidance on those options (1) and (2) above.

    Your contribution will be highly appreciated.

    This is covered by 341.3.3
    “Discontinuities detected outside the area required to be examined during weld joint examinations should be evaluated and resolved in a manner acceptable to the owner and designer.”
    How you practically implement this can be challenging.
