Product Description
Welding 2205 Duplex Stainless Steel:
-
Welding Processes:
- GTAW (TIG) and GMAW (MIG) are the most common welding processes used for 2205.
- SMAW (stick) and FCAW can also be used but require more careful parameter control.
-
Filler Metals:
- AWS A5.9 classification ERNiCrMo-3 (UNS W86112) is the most widely used filler metal.
- The composition should closely match the base metal to maintain the duplex microstructure.
-
Welding Parameters:
- Heat input should be carefully controlled between 0.5-2.5 kJ/mm.
- Inter-pass temperature should be limited to 150-200°C to avoid precipitating detrimental phases.
- Shielding gas should be pure argon or argon with 2-3% nitrogen.
-
Post-Weld Heat Treatment:
- Solution annealing at 1020-1100°C followed by water quenching may be required to restore corrosion resistance and mechanical properties.
Welding Duplex Stainless Steel Tubes and Pipes:
-
Tube/Pipe Welding Processes:
- Common welding processes include GTAW (TIG), GMAW (MIG), and FCAW.
- Automatic orbital welding is often used for consistent, high-quality welds on tubes/pipes.
-
Welding Parameters:
- Similar heat input and inter-pass temperature control as for 2205 plate welding.
- Shielding gas should be pure argon or argon with 2-3% nitrogen.
-
Filler Metals:
- ERNiCrMo-3 (UNS W86112) is a common choice, but other matching or slightly overmatching filler metals can also be used.
-
Post-Weld Heat Treatment:
- Solution annealing at 1020-1100°C followed by water quenching is often required for tubes/pipes.
-
Quality Control:
- Careful NDT (non-destructive testing) such as radiography, ultrasound, or dye penetrant is essential to ensure weld quality.
Product Characteristics
Okay, let's discuss the key product characteristics of 2205 duplex stainless steel:
-
Composition:
- 2205 duplex stainless steel (UNS S31803/S32205, EN 1.4462) has a balanced composition of:
- Chromium: 21-23%
- Nickel: 4.5-6.5%
- Molybdenum: 2.5-3.5%
- Nitrogen: 0.14-0.20%
- The balanced austenite-ferrite microstructure gives 2205 its unique properties.
