SW stands for which welding process?

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

Answer: (A)

Abbreviations for welding processes are a quick way to identify the method, and SW is the shorthand for arc stud welding. In arc stud welding, an electric arc is struck between a stud or fastener and the metal surface, fusing the stud to the work without a separate filler metal. The stud itself supplies the material that forms the joint, and the process is designed for rapid, localized attachment of bolts, nuts, or terminals, often with a capacitor-discharge or drawn-arc welder. This is different from shielded metal arc welding, which uses a consumable electrode and flux to shield the arc; from submerged arc welding, which welds along a seam under a flux blanket; and from air acetylene welding, which relies on a flame rather than an electric arc. So SW specifically points to arc stud welding.
