What is submerged arc-welding?


Submerged Arc Welding (SAW – Submerged Arc Welding in AWS terminology) is a continuous wire arc welding process under flux protection. In the Corimpex world, this type of welding is used to join steel plates in order to create complex components, for the subsequent production of structures, which require very high structural rigidity and an equally high quality of welding and production. The general morphology of the welding area (i.e. the fact that the arc works under the welding flux) allows to produce a large amount of heat which, being covered by the flux, remains localized in the welding bed in order to avoid chemical processes that can affect the quality of the weld itself. Submerged arc welding therefore allows to operate with high working and deposition speeds.  Submerged arc welding is a process that can be made fully automatic and can perform both vertical and horizontal beams and circumferential welds on rotators.
