Submerged Arc Welding (SAW in AWS terminology) is a continuous wire arc welding process under slag shielding.
The general morphology of the welding zone (i.e. the fact that the arc strikes under the slag) allows a large amount of heat to be generated which, being shielded by the slag, a poor heat conductor, remains localized in the weld pool. Submerged-arc welding therefore allows high welding and deposition speeds. Submerged-arc welding is a process that can be made fully automatic and can perform both longitudinal welds in a flat position and circumferential welds on positioners.
The purpose of our submerged arc vacuum cleaners is to recover the flux that has not turned into slag and return it to the tank of the welding machine to be reused in the cycle again. In addition, thanks to the screened filter in our hopper, we can separate from the flux any pieces of slag that might be sucked out of the system.
