Stud welding is not covered under CSA W48; it shall conform to which clause?

• A. 3.1.2.1
• B. 4.1
• C. 3.1.2.2
• D. 2.0

Answer: (C)

When a welding process isn’t specifically covered by a CSA standard like W48, the general requirements apply to ensure a consistent level of quality and safety. Clause 3.1.2.2 provides this fallback framework for welding procedures, workmanship, materials, inspection, and acceptance when a process or joint type isn’t addressed elsewhere. That’s why it’s the correct reference for stud welding in this context—it ensures the unaddressed process still meets the overall quality controls expected by CSA W59. The other clauses refer to different, more specific areas and don’t serve as the general fallback for a process not covered by W48.
