The common method used to start the SA arc
Submerged arc welding has consumable electrodes which are used for generating arc. The arc generates heat which forms the molten weld pool, the arc is covered in flux which protects the weld pool from surrounding gases. The weld pool consists of electrode and flux material in it.
The fused flux becomes slag which strengthens the joint. As the pool is covered with flux the loss in the molten weld is less...
