If the operator has not been involved in previous tests, how is the operator tested?

• A. Weld three studs and test them as required
• B. Weld two studs and test them the required way
• C. Take a written exam only
• D. Observe others welding

Answer: (B)

When someone is new to the testing program, the emphasis is on proving practical skill through a small, representative welding task that is then subjected to the required evaluation. The operator is asked to weld two studs, and those welds are tested using the approved procedure to demonstrate the ability to produce sound welds, maintain proper heat control, fit the joint, and follow the correct technique. This approach provides a tangible measure of capability without the extra workload of additional welds, and it ensures the tester’s competence before any broader duties are assigned.

Welding three studs would unnecessarily increase the scope of the test without adding more information about the operator’s actual skill. A written exam alone evaluates knowledge, not hands-on ability, and observing others welds does not prove the operator can perform or produce acceptable results themselves.
