If a welder holds a qualification for FW classification in a given process, are they automatically qualified for S classification in the same process, class and mode?

• A. Yes
• B. No
• C. Yes, but only for certain materials
• D. Only if the employer approves

Answer: (B)

In this standard, welder qualifications are tied to a specific classification and mode. A qualification for one classification does not automatically extend to another because the two classifications cover different scopes, joints, materials, and testing requirements. So even if a welder is qualified for FW in a given process, they must meet the separate testing and acceptance criteria to be considered qualified for the S classification in the same process and mode. A separate S qualification is required to demonstrate the ability to weld to the S-specific requirements.
