Question

For a CSA W59-compliant welding procedure to be considered prequalified:

a. It must be approved by the Canadian Welding Bureau (CWB)
b. It must meet specific requirements without the need for further testing
c. It must be used only for specific materials
d. It must undergo destructive testing before approval

Answer 1

Prequalified welding procedures under CSA W59 are procedures that meet the standard's specific requirements without needing further testing. They are limited to common applications as outlined by the standard.

Step-by-step explanation:

For a welding procedure to be considered prequalified in compliance with CSA W59, option b. 'It must meet specific requirements without the need for further testing' is the correct statement. Prequalification of a welding procedure according to CSA W59 means that the procedure has been established following certain rules and standard practices that have been proven to provide satisfactory welds. Consequently, such procedures don’t require separate qualification testing. It’s important to note that prequalified welding procedures are typically limited to common welding applications as defined by the standard, and they must adhere to the detailed guidance provided, including restrictions on joints, materials, and welding positions. Prequalified procedures are often used to ensure a certain level of proficiency and consistency in welding tasks without the additional time and expense involved in performing procedure qualification tests.
