Submerged Arc Welding (SAW)
Uses a continuous, consumable bare wire electrode, with arc shielding by a cover of granular flux
Electrode wire is fed automatically from a coil
Flux introduced into joint slightly ahead of arc by gravity from a hopper
Completely submerges operation, preventing sparks, spatter, and radiation
