SW is the acronym for which welding process?

• A. Arc stud welding
• B. Submerged arc welding
• C. Shielded metal arc welding
• D. Shielded metal arc cutting

Answer: (A)

Understanding welding process acronyms and what SW stands for helps you identify the correct process quickly. SW denotes Arc Stud Welding, a process that uses a high-current arc to weld a fastener stud to a base metal, typically without filler metal. The arc melts the stud tip and a small portion of the work surface, and when the arc is released the stud is drawn into the weld, forming a strong, flush joint suitable for mounting bolts or fasteners in assemblies. The other options describe different processes—Submerged Arc Welding (SAW) and Shielded Metal Arc Welding (SMAW)—and Shielded Metal Arc Cutting isn’t a standard welding process. Therefore, SW maps to Arc Stud Welding.
