Examination Records for CSA W178.2
CSA W178.2 names this requirement as "CWB Form 457, proof of continuing involvement in welding examination or testing". The employer's Level III owns it, alongside the certification scheme rather than replacing it.
The finding auditors record against this document is: Course with a built-in examination component claimed for recertification without evidence the examination was passed. CSA W178.2-18, published May 2018, certifies welding inspectors at three levels. Under Clause 4 the CWB administers the standard, assesses candidates, issues certificates and makes a public directory of certified inspectors available. The standard defines the technical duties at each level, sets experience and training prerequisites, prescribes the examinations including an open-book examination on at least one product code, sets a near-vision requirement, and fixes a three-year certificate validity with a six-year recertification cycle. Clause 1.6 draws the boundary that matters most to an NDT firm: W178.2 does not address certification of individuals performing radiographic, ultrasonic, eddy current, magnetic particle or liquid penetrant examinations.

| Regime | CSA W178.2, Certification of welding inspectors | Enforced by CSA Group publishes the standard; Clause 4.1 assigns administration to the Canadian Welding Bureau (CWB), which assesses candidates, issues certificates and maintains the public directory |
| Document | Examination Records | the general, specific and practical examination papers and results behind each certification |
| Owner | the employer's Level III | The signature an auditor traces back |
| Where it is checked | Renew every three years under Clause 10. | Usually against a sampled job, not in isolation |

What must a examination records contain under CSA W178.2?
It has to satisfy CSA W178.2 as CSA Group publishes the standard; Clause 4.1 assigns administration to the Canadian Welding Bureau (CWB), which assesses candidates, issues certificates and maintains the public directory enforces it: the general, specific and practical examination papers and results behind each certification. The test is not completeness on paper but traceability — an auditor picks a finished job and works backwards to this document, so anything it claims must be demonstrable on that job.
Who signs the examination records for CSA W178.2?
The employer's Level III. This regime requires central or third-party certification, so the signature works alongside the scheme rather than substituting for it.
How does a CSA W178.2 auditor test this document?
By sampling. They take a completed job, find the technicians and equipment used, and trace each back through this document to the evidence behind it. A document that reads well but cannot survive that trace is the most common finding across every regime, not just this one.
How long must CSA W178.2 records be kept?
Certificates are valid for three years (Clauses 9.1 and 10.1). Renewal is required every three years from initial certification and needs evidence of satisfactory vision and of continuing involvement in welding examination or testing; an inspector who does not renew before the expiry date is decertified. Recertification is required every six years from initial certification and is satisfied either by an examination on the visual detection, identification and descriptive reporting of weld faults, dimensional faults, material deficiencies and structural discontinuities and their assessment against defined acceptance criteria, or by 40 hours of instruction acceptable to the CWB completed within three years of the recertification date, in subjects such as visual welding inspection, non-destructive examination of welds, quality assurance or quality control, and codes and standards. A decertified inspector must rewrite all qualifying examinations for the level sought. Retention is set by the regime and by the client contract above it, and the longer of the two governs. Firms that set one retention period for everything and document it fare better at audit than firms tracking different periods per record type and losing track.
Does a generic template satisfy CSA W178.2?
No. A downloaded template describes a generic firm, and the first question an auditor asks is whether the document describes THIS firm — its methods, its equipment, its people, its actual workflow. Templates are a starting structure; the content has to be the firm's own or the trace fails immediately.
What happens if this document is missing at a CSA W178.2 audit?
It is a finding, and depending on the regime it can suspend the certificate rather than merely generate a corrective action. The related finding auditors record most often is: Level 1 inspector working without the qualified supervision Clause 5.3 requires

Personnel certification context
Central and third-party — the CWB is the sole administrator and assessor, and an employer-issued welding inspector certificate carries no standing under this standard. Clause 8.2.7 lets the CWB grant equivalent certification to the holder of a valid welding inspector certificate issued by another jurisdiction who has met requirements equivalent to Clauses 8.1 and 8.2, but that is a CWB decision, not an employer's. Clause 6 f) of the code of ethics requires an inspector to sign only for work he has inspected or has personal knowledge of through direct technical control, which sets a hard limit on how far any remote or outsourced signatory can go.
