    Study Notes

    Welding Test and Inspection Criteria

    • Acceptance criteria for discontinuities on the surface are specified: 3mm maximum in any direction, 10mm for the sum of discontinuities exceeding 1mm but less than or equal to 3mm, and 6mm for maximum corner crack, with exceptions.
    • Macro-etch test specimens for partial joint penetration and fillet weld test assemblies require two transverse sections of the weld to be cut, polished, and etched to reveal the weld fusion boundary.
    • Visual inspection requirements for macro-etched test specimens include fusion to the root of the joint, leg size conformity, actual effective throat thickness, and absence of cracks and undercut.
    • For plug and slot test assemblies, four transverse sections of the weld are cut, polished, and etched to reveal the weld fusion boundary, with specific visual inspection requirements.
    • Retests for soundness tests are mandated if the visual examination fails to meet the acceptance level, with different procedures based on the type of test specimen.
    • Mechanical tests include reduced section tension test specimens, with specific preparation and tensile strength requirements based on base material and filler metal strength.
    • For thicknesses over 38mm, individual reduced section tension test specimens may be cut into multiple specimens, with averaged tensile strength results required.
    • Retests for mechanical tests are allowed if the reduced section tension test specimens fail to meet the test requirements, with specific procedures for material over 38mm thick.
    • Welding consumables are addressed in the text, but the specific details are not included in the summary text provided.
    • The text includes references to specific figures and visual representations that are essential for understanding the testing and inspection criteria.
    • The text is part of a larger document with specific references to the date and licensing information, indicating its official and regulated nature.
    • The requirements outlined in the text are detailed and specific, ensuring the quality and integrity of the welding processes and materials.
