Submerged Arc Welding is a process where an electric arc is struck between a consumable electrode and the workpiece.

Here’s a basic breakdown of the setup of a sub arc welding torch:

1. Power Source: Provides the necessary electrical current to create the arc between the electrode and the workpiece.

2. Electrode: A continuous wire feed is used as the electrode. The wire is fed through the welding torch to provide a steady flow of filler material.

3. Welding Torch: This holds the electrode and directs it towards the workpiece. The torch also controls the delivery of the wire.

4. Flux Hopper: Above the welding area, there is a container called the flux hopper, which holds a granular substance known as flux. The flux is fed through a nozzle around the electrode, covering the arc and molten weld pool. The flux helps prevent oxidation and provides additional protection for the weld.

5. Workpiece: The metal that is being welded serves as the other part of the circuit. The electric arc melts both the electrode and the base metal, fusing them together.

6. Ground Clamp: A ground clamp is attached to the workpiece to complete the electrical circuit, ensuring the arc is formed correctly.
