SAW Submerged arc
High- basicity flux-cored wire for submerged-arc welding
Crane, automobile, equipment and steel construction, pipeline, foundries.
Crack resistant weld metal conditioned by the high-basicity slag in combination with very low hydrogen content. Well suited for the economic joining of high strength steels and cryogenic fine grain structural steels with Rp0,2 > 890 MPa (129 ksi). To reach the optimal mechanical properties, the energy absorbed per unit length of weld 15 kJ/cm should not be exceeded. The working temperature should be between 100°C (212 °F) and 150°C (302 °F). As welding flux FL 155 should be used because of its high basicity and low hydrogen content.
