- Applications
- WT-2209 is designed for the welding of 23% Cr-9%Ni-3% Mo duplex stainless steels and this principal area of application is chemical plant and shipbuilding as well as nuclear plant industries.
- Characteristics on Usage
-
- - WT-2209 is a rutile type flux cored wire for all-position welding.
- - It has low spatter generation, easy slag removal and good weld soundness.
- - It is excellent in pitting corrosion resistance and stress corrosion cracking resistance.
- 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.
