- Applications
- WT-347 is designed for the welding of 19%Cr-9%Ni-Nb stainless steels.
- Characteristics on Usage
-
- - WT-347 is a rutile type flux cored wire for all-position welding.
- - It has low spatter generation, easy slag removal and good weld soundness.
- - Nb component improves the resistance to intergranular corrosion of the weld metal
- -The weld metal contains optimum ferrite contents in their austenitic structures, Therefore their weldability is excellent with lower crack susceptibility.
- Notes on Usage
-
- - The shielding gas should be used 100% CO2 or Ar+20~25% CO2 for welding
- - Gas flow rate is proper 20~25ℓ/min.
- Sizes Available and Recommended Currents ( DC + )
