설명
특성:
LFC-711 is a flux-cored wire design to be use with CO₂ gas. It can be used on all-position
welding with both single and multiple pass welds on mild steels and 490N/mm² high tensile steel. With
good impact toughness, less fume, stable arc, easy slag removal and excellent X-Ray inspection.
애플리케이션:
It is widely used for shipbuilding, storage vessels, structural fabrication, machinery and piping etc.
사용 시 참고 사항:
- DC(+) 극성을 사용합니다.
- Use CO2 as shielding gas.
- In order to get enough penetration in the downhand weld position, maintain a little bit higher
welding speed by stringer manipulation for the first pass.
