Description
Caractéristiques :
LFC-811Ni2 is a titania type flux-cored wire.Use 100% CO₂ shield gas. It is designed for welding 590 N/mm² grade high tensile steel for low temperature.With good weldability ,stable arc, less spatter, good bead appearance and good impact toughness down to -40°C.
Applications :
It is suitable for welding on construction machinery, bridge,storage thanks and piping.
Notes sur l'utilisation :
1. Utiliser la polarité DC(+).
2 .Use 100% CO₂ shielding gas.
3. Pre-heat at 50-150℃ is required depending on steels, plate thickness and restraint.
4. Proper heat input can obtain required impact value.
5. Maintain interpass temperature under 150°C in multipass welding is good for mechanical property.
