During a routine audit of a certified welding company, it's discovered that a welder, qualified for SMAW in the 3F position, has been performing production welds in the 4F position without further qualification. Under CSA W47.1, what is the most likely consequence of this discovery regarding the welder's current qualification status for the 4F position?

Question: During a routine audit of a certified welding company, it's discovered that a welder, qualified for SMAW in the 3F position, has been performing production welds in the 4F position without further qualification. Under CSA W47.1, what is the most likely consequence of this discovery regarding the welder's current qualification status for the 4F position?

Answer options:

• The welder's 3F qualification is automatically extended to 4F. ✅ The welder's qualification requires immediate re-testing for 4F.
• The company receives a minor non-conformance that can be resolved with a written explanation.
• The welder's entire certification is revoked until all positions are re-tested.

Correct answer: The welder's qualification requires immediate re-testing for 4F.

Explanation: Under CSA W47.1, a welder qualified in the 3F (vertical fillet) position is not automatically qualified for the 4F (overhead fillet) position. Overhead positions often require specific skill and qualification, meaning additional testing would be required. This would be a clear non-conformance requiring corrective action.
