SAW stands for which welding process?

• A. Submerged arc welding
• B. Shielded metal arc welding
• C. Spot welding
• D. Shielded arc welding

Answer: (A)

SAW stands for Submerged Arc Welding. The defining feature is that a continuously fed wire electrode creates the arc, and a granular flux blankets the weld pool to shield it from the atmosphere, with the arc and weld submerged under the flux. This setup provides high deposition rates, deep penetration, and is well suited for automation on thick sections. The other options describe different processes: shielded metal arc welding uses a coated electrode with shielding from the flux but not a submerged blanket; spot welding is a resistance-type process for sheet metal; shielded arc welding is not a standard term for a separate process. Therefore Submerged Arc Welding is the correct interpretation of SAW.
