SAW is a unique welding method since it involves the arc which is completely submerged under the layer of granular flux. During welding, this flux that contains lime, SiO 2, MnO, CaF 2 and other compounds reacts with the contaminants in the molten weld metal and forms slag. Thus, slag is considered as waste material.

Submerged arc welding is a very useful and versatile welding method. The unused flux (that is not melted) is recovered for recycling. The submerged arc welding needs a continuous feed of consumable wire electrodes along with a continuous supply of the flux powder. The wire electrode can be a continuous solid or cored wire, or a strip.
