Submerged Arc Welding (SAW):
Uses an unshielded arc welding flux where the metal electrode and melt pool meet. On the workpiece the arc zone and melt pool are protected by being submerged under a covering of granular flux. The advantages of SAW include high deposition rates and high speed achieving high quality molten metal. |
