説明
特徴
LFC-309LMo is a modified type of LFC-309L with the addition of molybdenum. It designed for 100% CO₂ gas and all-position welding. It performs with smooth arc transfer, low spatter level, fast freezing slag and, good heat and corrosion resistance.
アプリケーション
It is suitable for weldingstainless steel to unalloyed steel. It is also used for buffer layers of clad steels.
使用上の注意
1. Use 100% CO₂ shielding gas.
2. Use DC(+) polarity.
3. Trailer Shield is required to ensure the weld pool completely shield until solidification is complete and no porosity problem.
4. To get enough penetration in the down hand welding position recommend maintaining a higher welding speed.
