Submerged Arc Welding
Submerged arc welding (SAW), also known as subarc, is a welding process that utilizes a continuously fed wire electrode and a blanket of fusible, granular material - commonly called flux - that is used for shielding the arc and molten metal. The arc is established between the work piece and wire electrode, the tip of which is submerged in the flux.
The high quality of submerged arc welds, high deposition rates, deep penetration, the adaptability of the process to full mechanization, and the operator comfort characteristics make submerged arc welding a preferred choice in steel fabrication. It is also a favored process for rebuilding and hardfacing.
Equipment required for submerged arc welding includes a power source, control unit, wire drive unit or head, flux storage, and nozzle (combines wire and flux in the joint). Automatic installations may require some form of propulsion to move the head along the joint or rotation of the item to be welded under a fixed head.
The most common submerged arc welding method used for single and multiple pass welds is one wire with one head. For high speed single pass and high deposition applications, look to two wires with one head (Lincoln's Twinarc® or Tiny Twinarc®). Multiple wires and heads are used for high deposition and large high travel speed joints (Lincoln's Tandem Arc process).
