Flux Cored Wires LFC-711M E71T-1M/9M

描述

特性:

LFC-711M is a flux-cored wire design to be use with Ar/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.

 

應用:

廣泛用於造船、儲存容器、結構製造、機械和管道等。

 

使用注意事項:

1. Use DC(+) polarity.
2. Use 75-85%Ar + 25-15%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.
