説明
特徴
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.
アプリケーション
It is suitable for butt or fillet welding for LNG and LPG carriers,storage thanks and low temperature service steel.
使用上の注意
1.DC(+)極性を使用してください。
2 .Use 100% CO₂ shielding gas.
3. Proper heat input can obtain required impact value.
