1. What base metals can ERNiCr-3 weld?

ERNiCr-3 is designed for Inconel 600, Inconel 601, Incoloy 800, and also for dissimilar welding between nickel alloys and stainless steels (e.g., 304, 316) or carbon steel.

2. Can ERNiCr-3 be used for cladding or overlaying?

Yes. It is often used for corrosion-resistant or high-temperature oxidation resistant overlays on carbon steel or low-alloy steel substrates.

3. What shielding gas is recommended for MIG welding with ERNiCr-3?

For GMAW (MIG), use 100% Argon or Ar + 20–30% He to improve wetting and penetration. For GTAW (TIG), use pure Argon.

4. Is preheating or post-weld heat treatment required?

Generally not required for most applications. However, for heavy sections or highly restrained joints, preheating (150–200°C) may be used to reduce thermal stress. Post-weld heat treatment is not typical for ERNiCr-3 weld metal.

5. What is the difference between ERNiCr-3 and ERNiCrMo-3?

ERNiCr-3 contains no molybdenum (Mo) and has higher niobium (Nb) content (2–3%), making it better for high-temperature oxidation resistance. ERNiCrMo-3 contains ~9% Mo, offering superior pitting and crevice corrosion resistance in chloride environments.

6. How should ERNiCr-3 be stored?

Store in a dry, clean environment. Once opened, if exposed to humidity, re-dry at 250–300°C for 1–2 hours or use within 8 hours to avoid hydrogen-induced cracking.

7. What is the typical interpass temperature for welding?

Keep interpass temperature below 150°C (300°F) to prevent overheating and loss of corrosion resistance.
