AIT Welder 2nd Period Practice Test

Post-weld inspection starts with cleaning the weld area so flaws aren’t hidden by oil, scale, or debris. Visual inspection then checks for surface defects, weld geometry, alignment, and evidence of poor technique, guiding whether further testing is needed. Measuring dimensions confirms the weld size and fit to drawings and specs. If codes or service requirements call for it, nondestructive testing is performed next, using methods like ultrasonic testing or radiographic testing to detect internal or hidden flaws; other methods may be used for surface indications. Finally, all results are documented, and any needed repairs are identified and marked for follow-up re-inspection after remediation. This order ensures surface and dimensional quality are verified before relying on internal flaw detection, and it preserves traceability and accountability. Coating before inspection would hide defects; relying only on radiography would miss surface issues; polishing and forgetting provides no assessment of weld quality.
