SUBMERGED ARC WELDING

The optimum performance of welded vessels and structures in service have led to the full exploitation of automatic welding processes. This arc welding is one of the automatic welding processes. Submerged arc welding has been playing a prominent role in it's endeavours and it finds application in a variety of components from pressure vessels, structures, machine building elements, hard facing of components exposed to wear, etc. In submerged arc welding operation, the heat energy for welding is supplied by an arc, developed between a consumable electrode and the work piece under a blanket of welding flux.
