Arc / Sub-Arc Welding Services • • •
Submerged arc welding (SAW) is so named because the weld and arc zone are submerged beneath a blanket of flux. The flux material becomes conductive when it is molten, creating a path for the current to pass between the electrode and the workpiece. The flux blanket prevents spatter and sparks, while shielding ultraviolet light and fumes that are normally a part of shielded metal arc welding. The flux usually is supplied to the welding head via a small hopper. A collection system gathers the excess flux for reuse.
The process uses one or more continuously fed electrodes (wires) to maintain an arc. SAW is known for its ability to deposit large amounts of metal quickly, consistently, and safely. The basic SAW equipment is a power source, control unit, wire unit, and nozzle
