Beschreibung
Merkmale:
LFC-811K2 is a titania type flux-cored wire. Use 100% CO₂ shield gas. It is designed for welding 560 N/mm² grade high tensile steel for low temperature. The weld metal contains 1.5%Ni and makes good impact toughness down to -60°C. With good weldability, stable arc, less spatter in all position welding.
Anwendungen:
It is suitable for butt or fillet welding for LNG and LPG carriers,storage thanks and low temperature service steel.
Hinweise zur Verwendung:
1. Use DC(+) polarity.
2 .Use 100% CO₂ shielding gas.
3. Proper heat input can obtain required impact value.
