ROYAL ARCPRO 8

AWS/ASME: A5.17 EL8

ROYAL ARCPRO 8 is a mild steel submerged arc welding wire (SAW) classified as EL8.
Designed for welding carbon steels and low alloy steels.
Produces welds with smooth bead appearance and good slag detachability when used with appropriate SAW fluxes.
Offers high deposition efficiency and consistent wire feeding.
Widely used in structural fabrication, shipbuilding, pressure vessels, and general engineering.
Suitable for single and multi-pass welding in flat and horizontal positions.
