Properties And Applications

Alumina-basic type, agglomerated submerged arc welding flux, developed particularly for spiral and longitudinal welding of pipes. It gives the possibility of high-speed welding in the welding of thin and medium thick pipes by single or multi-wires (tandem/twin). Bead appearence is good. Especially in pipe welding, inner and outher welds are smooth and provide necessary penetration. It has high current carrying capacity and can be used in alternative and direct currents. Provides smooth weld beads, good weld bead appearance with high penetration.
