- Applications
- LNG and LPG storage plant, boilers of thermal power station.
- Characteristics on Usage
-
- - It can be used for dissimilar welding between nickel-chromium-iron alloys to mild steels or stainless steels.
- - It is similar to 182 but with lower Mn and Mo addition, Mo and Nb are added to give high resistance to hot cracking and tolerance to dilution.
- Notes on Usage
-
- - Use Ar+20~25% CO2 gas.
- - The optimum flow of CO2 for shielding is 20~25ℓ/min.
- Sizes Available and Recommended Currents ( DC +)
