High-deposition, automated arc welding beneath a protective flux blanket — built for thick-section structural steel, pressure vessels, and long production welds.
Submerged Arc Welding strikes an arc beneath a continuously fed, granular flux blanket rather than in open air. The flux fully covers the arc and weld pool, virtually eliminating spatter, arc flash, and fume exposure while allowing significantly higher amperage — and therefore much higher deposition rates — than open-arc processes.
That combination of high deposition and a smooth, self-cleaning slag makes SAW our process of choice for heavy-plate structural steel, pressure vessel shells, and other applications where weld volume and repeatability matter as much as strength. The process is fully mechanized, holding travel speed, arc voltage, and wire feed to tight, repeatable tolerances across long production welds.
A mechanized, flux-shielded process built for heavy-section production welding.
The joint is prepared and a granular flux bed is laid ahead of the welding head.
A bare wire electrode feeds continuously into the flux-covered joint.
The arc burns fully submerged beneath the flux, shielding it from the atmosphere.
