Oerlikon Fluxofil 43.1 description: FLUXOFIL 43.1 is a seamless copper coated basic flux cored wire used for the welding of high-strength fine grain structural steels which are normalized (N) or normalized + tempered (N + T) after welding. The heat treatment
required depends on the base metal being welded. The weld metal is not recommended for use in the as-welded or stress relieved conditions. Quiet and smooth running with low spatter loss and easy slag removal produces uniform and smooth beads which are free from porosity. To be used under Ar/CO2 gas.
