A neutral, semi-basic agglomerated flux of the aluminate basic type suitable for joint welding of low-alloy structural steels, fine-grained steels and pipe steel qualities. Designed for DC and AC welding
EN 760: SA AB 1 67 AC H5 is suitable for the two-run or multi-layer technique using single or multi-wire processes. The flux shows constant metallurgical characteristics (low Silicon and Manganese pick-up). In combination with appropriate wires, such as Mo-, Ni- or NiMo-alloyed types, uniform mechanical properties with low temperature toughness are achieved. Slag–detachability, even in narrow–groove welds of thick-walled sections, or at high preheating temperature (> 250°C), together with finely rippled weld bead performance and smooth tie–ins, even when fillet welding using high currents, are additional features of the flux.EN 760: SA AB 1 67 AC H5 is formulated to achieve very low diffusible hydrogen levels (< 4 ml/100 g weld deposit).The chemical com position of the flux, respectively its alloy vector, has been designed for achieving large amount of acicular ferrite with typical standard wires.
