SAW Submerged arc

Agglomerated semi-basic flux suitable for carbon alloy steel welding in single and multi-pass technique and in single or multi-wire applications. The weld deposit produced in combination with corresponding sub-arc wires meets outstanding mechanical properties and in particular high toughness at low temperature. Excellent slag removal in fillet and groove (semi-narrow gap) welds even in hot conditions. (Pre heat 250°C) This flux is specially developed to achieve very low content of diffusible hydrogen (< 4ml/100 g weld deposit)
 

Submerged arc welding wire for fine grain steels where high impact values are required at low temperatures.

Fused flux with neutral caracteristics (Mn and Si) for aplications when redrying is not easy to apply. Fused fluxes offers excelent resistance against moisture pick up.

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 we recommend our type ST 55
