설명
특성:
LFC-711Ni is a flux-cored wire design to be use with CO₂ gas. It can be used on all-position welding on 490N/mm² high tensile steel. With stable arc, less spatter, easy slag removal and excellent X-Ray inspection. It provides good low-temperature impact value due to 0.4%Ni in weld metal.
애플리케이션:
It is widely used for shipbuilding, vessels, piping, off-shore plateform, low temperature service storage tanks, etc.
사용 시 참고 사항:
1. Use DC(+) polarity.
2. Use CO₂ as shielding gas.
3. In order to get enough penetration in the down hand weld position, maintain a little bit higher welding speed by stringer manipulation for the first pass.
4. Keep dry during handling and storage.
