When welding structural steel in the field, the welder's certification has expired. What is the appropriate course of action before allowing any welding to proceed?
Correct Answer
C) Require re-certification testing before any welding begins
AWS and building codes require current welder certification for structural welding. Expired certifications must be renewed through proper testing procedures before any structural welding is permitted, regardless of supervision or connection criticality.
Why This Is the Correct Answer
AWS D1.1 (Structural Welding Code) and applicable building codes require current, valid welder certification for all structural welding. An expired certification means the welder's qualifications are no longer recognized. The only compliant path is to stop all welding and require the welder to pass re-qualification testing before any work resumes.
Why the Other Options Are Wrong
Option A: Document the expired certification and proceed with extra inspection
Documenting the expired certification and proceeding with extra inspection does not resolve the compliance issue. Inspection cannot retroactively validate uncertified work, and proceeding knowingly with an uncertified welder exposes the contractor to serious liability.
Option B: Permit welding of non-critical connections only
There is no code distinction that permits uncertified welders to perform 'non-critical' connections. All structural welding requires certified welders — the term 'non-critical' is not defined in AWS D1.1 as a category that bypasses certification requirements.
Option D: Allow welding to continue under supervision of a certified welder
Supervision by a certified welder does not extend that welder's certification to another person. Each individual performing structural welds must hold their own current certification. Allowing an uncertified welder to proceed under supervision is a code violation.
Memory Technique
No cert = No weld, period. The expired certification is a hard stop — not a yellow light. Think of it like a driver's license: a supervisor in the passenger seat doesn't make an unlicensed driver legal.
