Properties And Applications

Alumina-basic type, agglomerated submerged arc welding flux, which is developed for single- and multi-wire (tandem) welding of butt and fillet joints in shipbuilding, steel constructions, storage tank and machine production. Suitable to use in single and multi pass welding in thick and thin sections. Due to it's metallurgically neutral characteristics, there is low Si and Mn pick-up from flux, it can be safely used in multi-pass applications in thick sections. Has a high current carrying capacity and possible to use both in alternative and direct currents. Provides brigth and very clean weld surface appearence with easy slag removal in fillet joints and narrow V-groves.
