Properties And Applications

Alumina- basic type, agglomerated submerged arc welding flux, which is designed for single or multi pass welding of butt and fillet joints in high strength steels. Especially designed for thick section welding in steel construction, wind tower, boiler and pressure vessel production. Provides high toughness values down to -50°C. Due to it's high current carrying capacity and good operating characteristics both on alternative and direct currents, possible to use in one side welding and two side welding processes by single or multi-wires (tandem/twin). Has high penetration and smooth weld beads with easy slag removal in fillet and V-groves.
