Oerlikon Fluxocord 42 description: FLUXOCORD 42 is a seamless copper coated basic flux cored wire for submerged arc welding on high-strength fine-grain structural steels in combination with OERLIKON OP 121TTW. The weld metal composition obtained with
FLUXOCORD 42 / OP 121TTW meets the mechanical property requirements in both the as welded and stress relieved conditions. The weldability of high yield strength steels is in general strongly depending on the dilution rate with the base metal (incl its composition) and the cooling rate of the weld cycle (t8/5: heat input, interpass temperature, plate thickness).
