The submerged arc welding process (SAW) is used to fuse metal pieces by producing an electric arc between an electrode wire with continuous wire feed and a base metal.
The electric arc is produced beneath a layer of granular flux which is laid down on the joint to be welded. The flux protects the fusion bath against the oxidizing ambient atmosphere. It also eliminates the welding splatters and the ultraviolet ray emissions.
Submerged arc welding is generally used for the fabrication of large pieces.
This is a reliable and robust welding process, which allows us to achieve very good quality welds with high-level productivity.
Submerged arc can be used with different types of currents:
We find different variables within the submerged arc welding process.
Here are a few:
Submerged arc welding has certain limitations; it can only be used in a flat and horizontal position. It could be used as a semi-automatic process, but it is generally operated as a fully-mechanized or automatic process to weld linear assemblies.
This is the ideal welding process for bridge superstructure manufacturing and largescale structural steel.
