Description
Characteristics:
LFC-316L is designed for 100% CO₂ gas and all-position welding. It performs with excellent slag removal, almost spatter-free and high intergranular corrosion resistance to pressure vessel application.
Applications:
It is suitable for welding 18%Cr-12%Ni-2%Mo stainless steel including type of 316, 316L, CF-8M and CF-3M.
Notes on Usage:
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.
