 Description and Applications
 An agglomerated aluminate-basic type non-alloyed flux for submerged
 arc welding SUBTECH-66 is specially developed for single or multipass butt
 welding and fillet welding of structural steels, pipe steels, ship steels and
 high tensile strength steels. Typical application areas are the longitudinal
 welds and circumferential welds of pressure vessels and storage tanks.
 It provides pores free welds and good appearance weld beads, easy
 removable slag. The flux has to re bake between 300-350ºC before
 welding.
