CSA W59.2 Welded Aluminum Construction allows the use of which of the welding processes below?

• A. Submerged Arc Welding
• B. Stud Welding
• C. Electrogas Welding
• D. Flux Cored Arc Welding

Answer: (B)

CSA W59.2 Welded Aluminum Construction recognizes stud welding as an approved method for aluminum construction, particularly for attaching fasteners and hardware to aluminum members. Stud welding is well-suited for thin sections, minimizes heat input, and can produce consistent, reliable joints when the base metal and stud meet the specified thickness and material requirements. The other processes listed are not the methods the standard designates for aluminum structural work in this context, due to practical limitations with aluminum oxide, fusion behavior, or coverage within this standard. So, stud welding is the method that fits the CSA W59.2 allowances for welded aluminum construction.
