ERNi-1 welding wire is a nickel-based filler metal specifically engineered for welding pure nickel (Ni 200/201) and nickel alloys, offering exceptional resistance to alkaline and high-temperature corrosion. Composed of a minimum 93% nickel content with titanium stabilization (2.0–3.5%), this wire minimizes carbon reactivity to prevent sensitization and intergranular attack in corrosive environments such as chemical processing, marine engineering, and thermal power plants. Its low iron (≤1%) and sulfur (≤0.015%) content ensures clean, crack-free welds with tensile strength exceeding 414 MPa and elongation ≥20%, making it ideal for applications requiring durability under cyclic thermal stress.
Certified to AWS A5.14 and ASME SFA-5.14 standards, ERNi-1 excels in gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and submerged arc welding (SAW) when paired with INCOFLUX 6 flux. The alloy’s versatility extends to joining nickel alloys with stainless steel, carbon steel, and copper-nickel alloys, ensuring robust metallurgical compatibility in mixed-material systems. With a melting range of 1,370–1,430°C and thermal conductivity of 14.8 W/m·K, it maintains stability in high-temperature operations up to 600°C, outperforming conventional stainless steel wires in aggressive media like chlorides and alkalis.

Chemical Processing: Reactors, valves, and pipelines handling caustic soda, sulfuric acid, and chlorides.
Marine Engineering: Offshore platforms, seawater heat exchangers, and desalination systems.
Power Generation: Boiler components, flue gas scrubbers, and nuclear reactor cooling systems.
Oil & Gas: Sour gas pipelines and LNG storage tanks in H₂S-rich environments.
Dissimilar Metal Joining: Bridging nickel alloys with carbon steel, stainless steel, and Monel alloys.
Q1: Can ERNi-1 wire be used for submerged arc welding (SAW)?
A: Yes. ERNi-1 requires INCOFLUX 6 flux for SAW to ensure optimal slag formation and weld purity, particularly for Nickel 201 alloys.
Q2: Does ERNi-1 require preheating for welding nickel alloys?
A: Preheating is generally unnecessary due to low carbon content. However, post-weld stress relief (650–870°C) is recommended for thick sections to prevent cracking.
Q3: Is ERNi-1 compliant with NACE MR0175 for sour service applications?
A: While ERNi-1 is optimized for alkaline corrosion, its low sulfur content and titanium stabilization align with NACE standards for moderate H₂S environments.
