What does SAW stand for?

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

Answer: (A)

SAW stands for Submerged Arc Welding. In this process, the welding arc is buried under a blanket of granular flux, which melts to form a protective slag that shields the molten weld from the air. A continuous filler wire is fed into the joint, allowing very high deposition rates and making it ideal for welding thick sections and long welds. The shielding isn’t from a gas around the arc, but from the flux beneath the surface, which is what gives it the “submerged” name. The other options don’t fit SAW because they describe different welding concepts: spot arc welding refers to localized spot welds, shielding arc welding isn’t the standard term for this method, and standard arc welding isn’t a recognized process name.
