Welding processes not covered by CSA W59 or not written into this standard fall under the acceptance criteria of which standard?

• A. CSA W59
• B. CSA W48
• C. CSA W60.1
• D. CSA W47.1

Answer: (D)

When a welding process isn’t specified or covered in CSA W59, the acceptance criteria you use come from the welder qualification standard. CSA W47.1 governs how welders are qualified for fusion welding of steel, including the performance tests and certification that demonstrate a welder can produce sound welds. If a process falls outside what W59 enumerates, you rely on W47.1 to establish what constitutes an acceptable weld through the welder’s demonstrated capability. The other standards focus on different scopes or materials and don’t provide the appropriate acceptance criteria for processes not listed in W59.
