Agglomerated aluminate-basic type flux for welding of medium tensile and pipe steels up to X70 grade. AP380 produces a slight silicon and manganese pick-up.Owing to its metallurgical behavior, it can be used with S2Mo and S3Mo wire electrodes. The flux is suitable for longitudinal and spiral welding of pipes.The flux has a high current carrying capacity and as such is suitable for fillet and butt-welding applications especially for weld in heavy section steels work. The weld bead is of uniform profile with smooth weld bead profile and good blending at the weld toes even at high welding speeds.The slag detachment is good and in most cases is self-lifting.AP380 can be used on either. DC+ or AC up to 1200 A on a single wire.
