Applications and Properties
Solid, submerged arc welding wire suitable <strong>for</strong> welding general structural steels with medium and high tensile strength, used in pressure vessel, boiler, pipe, shipbuilding and steel constructions. Higher silicon
content improves deoxidation of weld pool. Copper coating increases electrical conductivity and resistance against rusting.
