Which of the following is a condition under which the Canadian Welding Bureau may revoke a welder's qualification?

• A. Not engaged in a given process for 3 months or more
• B. Not engaged due to annual leave
• C. Moving to a different company within 2 weeks
• D. Completing a qualification check test

Answer: (A)

The concept here is that a welder’s qualification must reflect current ability in the specific welding process. If the welder stops performing that process for an extended period, the CWB may revoke the qualification to ensure weld quality remains up to date. Three months or more of inactivity is the threshold where, to maintain safety and reliability in welds, the qualification can be withdrawn unless the welder requalifies before returning to that process.

Annual leave is a temporary absence and doesn’t automatically reset or revoke qualifications. Moving to a new employer doesn’t in itself invalidate a qualification. Completing a qualification check test is the opposite of revocation; it’s a step toward verifying or renewing competence.
