In submerged arc welding, the welding current flows through which component to reach the weld puddle?

• A. Solid wire
• B. Shielding gas
• C. Flux
• D. Base metal

Answer: (A)

In submerged arc welding, the current is carried directly by the consumable electrode wire. The wire is fed into the arc from the power source, delivering heat to the tip and into the weld puddle. Shielding gas isn’t used in SAW, and the flux blanket mainly provides shielding and slag protection rather than conducting the current. The base metal is the workpiece where the weld forms, with the electrical return path completing the circuit via the machine setup. So the current reaches the weld puddle primarily through the solid electrode wire.
