Introduction to SAW 263
This class describes submerged arc welding (SAW) and the modes, equipment, and consumables it uses. In SAW, the arc and weld puddle are buried under a blanket of loose flux material. The consumable electrode is a continuous wire fed through a welding gun or welding head, depending on the SAW mode. SAW modes include semi-automatic and automatic. Automatic SAW is the most common mode. The mode also affects the specific equipment in an SAW system, but all systems require a power source, a wire feeder, and a flux delivery system.
Although SAW can only be performed in the flat or horizontal position, it has many other advantages. The blanket of flux thermally insulates the weld, which helps prevent discontinuities, and the high current results in excellent weld penetration. These benefits make SAW a popular choice for a range of applications. After taking this course, users will have the foundational understanding necessary to safely and effectively perform SAW.
