SW 702Si


EN ISO 14171-A S2Si
TS EN ISO 14171-A S2Si

Properties And Applications

Solid, submerged arc welding wire suitable for welding general structural steels with medium and high tensile strengths, 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.
