Seamless all positional metalcored high efficiency wire especially designed for semi-automatic and fully automatic joint welding of unalloyed and fine-grained constructional steels. Seamless technology guarantees a higher wire rigidity that give- as benefits- exact ignition and positioning accuracy. Very high metal recovery between 95 and 97% are additional benefit of this wire. Steady spray arc-like droplet transfer with minimal spatter formation, good penetration, high resistance to porosity, good behavior as well as low hydrogen contents (~ 2ml/100g weld deposit) are further quality features of this metalcored wire. Minimum oxide residues permit the welding of multi passes without the need for inter-run cleaning. Ideal for horizontal and flat fillet welds.
