Description
Characteristics:
LFC-811W2 is a titania type flux-cored wire. Use 100% CO₂ shield gas.With excellent mechanical property, good weldability ,stable arc, less spatter and smooth bead appearance in all position welding.
Applications:
It is suitable for butt or fillet weldingof 590 N/mm² weather–proof grade steeland ASTM A588, A242, A333 or COR-TEN 60 (used normally without painting)
Notes on Usage:
1. Use DC(+) polarity.
2 .Use 100% CO₂ shielding gas.
3. Proper heat input can obtain required impact value.
4. Preheat is required and interpass Temperature should be controlled around 50-150°C.
