HiCOP Tank Duplex
- Good weldability
- TIG-GTAW, Laser and PAW most common
- Use filler metal: Avesta LDX 2101® / 22 9 3 NL
- Nitrogen additions to shielding / backing gas gives positive effect on strength and corrosion resistance
- Shielding gas (TIG)
- Backing gas (TIG)
- Post weld heat treatment not necessary
- Use back gas also when repair and tcak welding
- LDX2101 is suitable for autogenously welding and welding without filler
- Welding decreases corrosion resistance! Effect less with good backing gas shielding. Post weld cleaning is recommended
