Must all welding personnel qualification testing be witnessed by the Canadian Welding Bureau?

• A. Yes
• B. No
• C. Only the radiographs
• D. Only for the initial qualification tests

Answer: (B)

Not every welding personnel qualification test has to be witnessed by the Canadian Welding Bureau. The standard allows qualification tests to be conducted in-house under an approved program with a qualified supervisor, as long as the testing follows the required procedures and results are properly documented and traceable. The CWB’s role is to certify welders and to witness or audit tests as needed for verification, not to attend every single test. Radiographic testing is a separate nondestructive inspection step and is not the same thing as witnessing the welding qualification test. So, the blanket requirement that all qualification tests must be witnessed by the CWB isn’t accurate.
