Incomplete Inspection Records and Traceability
You are reviewing the final documentation package for a welded vessel before hydrotest. The package contains WPSs, PQRs, welder qualification records, and visual inspection reports. You notice that one visual inspection report for a longitudinal seam lists the weld as "acceptable" but has no inspector signature, no date, and no record of the specific undercut or reinforcement measurements. The report references a drawing revision that is two revisions older than the current drawing. The welder qualification for the welder who made that seam expired three weeks before the weld date, though it was renewed two weeks after. The vessel is scheduled for hydrotest tomorrow. The code requires documented visual examination by qualified personnel and traceability of welds to qualified welders.
1. Identify each documentation deficiency and explain why it matters for code compliance.

Deficiency 1 - Unsigned, undated visual report with no measurements. The code requires visual examination to be performed and documented by qualified personnel. An unsigned, undated report cannot establish who inspected the weld or when, and without recorded measurements (undercut depth/length, reinforcement height) there is no evidence the acceptance criteria were actually applied. "Acceptable" alone is an assertion, not a record. This is a traceability failure.
Deficiency 2 - Report references a superseded drawing revision. The inspection was apparently performed against an older revision, which may have different weld sizes, joint details, or acceptance criteria. If the drawing changed, the inspection may not have covered the current requirements. The report must be reconciled to the current revision or the weld re-inspected against it.
Deficiency 3 - Welder qualification expired at the weld date. The welder's qualification lapsed three weeks before the weld and was renewed two weeks after. At the time of welding, the welder was not qualified, which is a direct code violation regardless of the later renewal. Renewal after the fact does not retroactively qualify the weld. The weld must be treated as made by an unqualified welder - typically requiring re-qualification of the weld by examination or replacement.
Each deficiency independently blocks hydrotest sign-off.
2. What actions must be taken before the hydrotest can proceed, and in what order?
Read the worked answer
Order of actions:
- Stop and quarantine. Do not proceed to hydrotest. Flag the vessel and the affected seam in the documentation system.
- Resolve the welder qualification issue first, because it determines whether the weld itself is acceptable. Determine whether the welder was qualified under a different valid record at the weld date (check all records - sometimes a second qualification exists). If not, the weld must be examined per the code's requirements for welds made by unqualified welders; this usually means volumetric examination and/or re-welding by a qualified welder. The post-dated renewal does not cure the gap.
- Re-inspect the seam against the current drawing revision. Perform a fresh visual examination by a qualified inspector, record undercut, reinforcement, leg size, and length measurements, sign and date the report, and reference the correct revision.
- Reconcile the documentation package. Replace the deficient report, attach the correct drawing revision, and ensure every weld is traceable to a qualified welder and a qualified WPS.
- Obtain sign-off from the responsible inspector and, where required, the authorized inspector before scheduling hydrotest.
Only after steps 2-4 are closed should the hydrotest be rescheduled. Proceeding tomorrow would create a nonconformance that could invalidate the vessel's certification.
3. The project manager argues the welder's renewal two weeks later proves competence, so the weld should be accepted. How do you respond?
Read the worked answer
The argument confuses demonstrated competence with documented qualification at the time of work. Code compliance is point-in-time: the welder must hold a valid qualification on the date the weld is made. A renewal two weeks later shows the welder can pass a test, but it does not certify that the specific weld in question was made under a qualified procedure by a qualified welder on the date recorded.
Several practical reasons reinforce this:
- Continuity and condition: A lapsed qualification may reflect a gap in practice; the renewal test was performed under test conditions, not production conditions.
- Traceability: The code's record system exists so that every weld can be tied to a qualification valid on its date. Accepting retroactive renewal undermines the entire traceability chain and would not survive an audit.
- Precedent: If one weld is accepted on this basis, the fabricator has no incentive to maintain currency, and the inspection system loses credibility.
The correct path is to treat the weld as made by an unqualified welder and apply the code's remedy (examination and/or re-welding). I would document the PM's position and my rejection in writing so the decision is transparent, and escalate to the authorized inspector if the PM insists on proceeding.
