ERNi-1 MIG & TIG Welding Wire

The ERNi-1 MIG & TIG Welding Wire welding wire, offered by Metals And Welding Specialities, is a high-quality nickel-based alloy filler metal designed for exceptional corrosion resistance and superior weldability. Engineered with precision, this filler wire corresponds to UNS N02061 and meets the standards of ASTM Grade ERNi-1. It is primarily used for welding wrought or cast nickel materials such as Nickel 200 and Nickel 201. Known for its purity and excellent mechanical strength, this alloy is widely applied across industries that demand reliability in harsh and corrosive environments.

Metals And Welding Specialities ensures that every spool of ERNi-1 MIG & TIG Welding Wire wire meets international quality specifications, offering consistent chemical composition and excellent performance under both high and low temperature conditions. The filler metal provides outstanding resistance to a range of chemicals including hydroxides, fluorides, and neutral or alkaline salt solutions. Its unique metallurgy allows welders to achieve clean, porosity-free welds with remarkable ductility and toughness, making it a preferred choice for critical fabrication tasks.

One of the key advantages of ASTM ERNi-1 is its exceptional corrosion resistance in caustic and reducing environments, a property that stems from its high nickel content. This makes it particularly suitable for process equipment used in the chemical, food processing, marine, and aerospace industries. It also performs reliably in the manufacturing of heat exchangers, piping systems, storage tanks, and other pressure vessels exposed to corrosive media. The filler metal produces smooth, stable arcs in both MIG (GMAW) and TIG (GTAW) processes, ensuring easy handling and consistent bead appearance.

With UNS N02061 classification, the ERNi-1 wire provides exceptional versatility, allowing it to be used for joining dissimilar metals such as nickel to stainless steel or copper alloys. Its low carbon content prevents carbide precipitation, minimizing the risk of intergranular corrosion. Moreover, the filler metal maintains its mechanical integrity even under elevated temperatures, offering long-term durability and stable performance.

As a trusted supplier of specialty welding consumables, Metals And Welding Specialities manufactures and supplies ERNi-1 MIG & TIG Welding Wire filler wire with stringent quality control and precision packaging to ensure optimal weldability and customer satisfaction. Each batch undergoes rigorous testing to verify its composition, mechanical properties, and surface finish. The result is a premium-grade welding wire that guarantees superior weld quality, long service life, and dependable performance in demanding industrial applications.

Metals And Welding Specialities’ commitment to excellence ensures that clients receive not only a product but a complete welding solution that enhances efficiency and productivity across all fabrication environments. When it comes to high-performance nickel alloy welding wires, ERNi-1 MIG & TIG from Metals And Welding Specialities stands as the benchmark for precision, purity, and durability.
