- Applications
- WT-625 is designed for welding of Inconel 600 + 625 and Nickel alloys, 9% Nickel steels.
(LNG storage tank manufacture, desulfurization, Heat exchanger, Building of chemical carrier)
- Characteristics
-
- - It can be used for surfacing of 9% Ni steels or dissimilar welding of Inconel to stainless steels.
- - The weld metal has high strength at room and elevated temperatures and has exceptional corrosion resistance.
- Notes on Usage
-
- - Use 100% CO2 or Ar+20~25%CO2 gas.
- - Gas flow rate is proper 20~25ℓ/min
