Submerged Arc Welding (SAW)

Submerged Arc Welding (SAW) is an advanced welding process used mainly for constructing large metal structures. It involves feeding a continuous wire electrode into the weld area, where an arc forms between the wire and the workpiece to melt and join the metals. The process is performed under a blanket of granular flux, which shields the molten metal from contamination, ensuring a strong, high-quality weld. SAW is efficient, produces deep welds, and is often automated, making it ideal for heavy-duty applications like shipbuilding, pressure vessels, and structural steel fabrication.
