Submerged Arc Welding

An arc welding process that uses an arc or arcs between a bare metal electrode or electrodes and the weld pool. The arc and molten metal are shielded by a blanket of granular lux on the workpieces. The process is carried out without the application of pressure and with a filler metal from the electrode and sometimes from a supplement source (welding rod, lux, or metal granules).
