Submerged Arc Welding (SAW)

Submerged arc welding (SAW) is an arc welding process with high deposition rate. The flux protects against oxidation and absorbs radiant energy, improving temperature control.

Physical-Chemical Mechanism of Action

Submerged arc welding (SAW) uses a layer of granular flux that completely covers the arc. The flux absorbs radiant energy and protects the workpiece from oxidation. The high deposition rate allows for fast processing.

Metallurgical Relevance & Risks in Welding

Proper SAW application improves temperature control and prevents porosity. Incorrect flux amounts or a missing protective layer can lead to uneven processing and cracks.

Workshop Practice & Instructions

Use a flux layer thickness of 1 to 2 mm. Make sure the flux is fine and evenly distributed. Cool the workpiece slowly after welding to avoid porosity.
