What is Submerged Arc Welding (SAW)?

Submerged Arc Welding (SAW) is a welding process where an electric arc forms between a continuously fed electrode and the workpiece. This arc is covered by a layer of powdered flux, which, when melted, conducts electricity between the electrode and the metal being welded. The flux also produces a protective gas shield and a layer of slag, both of which safeguard the weld area.

What is a SAW Welding Machine?

A SAW (Submerged Arc Welding) welding machine is a device used to perform submerged arc welding. It feeds a continuous electrode wire and a blanket of powdered flux to create a weld. The machine ensures that the arc, which forms between the electrode and the workpiece, is submerged under the flux. This setup facilitates the welding process by providing electrical conduction, generating a protective gas shield, and forming a slag layer to protect the weld zone.
