Submerged arc is a mechanized process, where one wire is fed through a conduit and a contact nozzle up to the welding arc. The arc and the molten pool are protected by a mineral flux supplied in front of the wire, this melts and creates a slag which also contributes to a particularly smooth and even weld surface. Submerged arc welding is suitable for most unalloyed and alloyed types of steel. The process stands out by its good welding economy, which is caused by a high deposition rate, and in general few welding defects. Submerged arc is also extensively used for cladding, where wear resistant or corrosion resistant metals are deposited onto ordinary steel.
