A welder's qualification remains in effect for how long?

• A. One year
• B. Two years
• C. Five years
• D. Indefinitely

Answer: (B)

Welder qualification is time-limited to keep skills aligned with current procedures and quality expectations. In CSA W47.1-09, the qualification remains in effect for two years from the date of qualification. After that period, the welder would need to be requalified if they intend to continue production welding under the same qualified conditions. This two-year window helps ensure welders stay proficient with the processes, materials, and joint details they're certified to weld; longer or indefinite validity would risk drift in skill and consistency.
