ERNi-1 is a pure nickel-based welding wire (AWS classification) with titanium, used for welding pure nickel (Ni 200/201) to itself, joining nickel to carbon/stainless steels, and for steel overlays, providing excellent corrosion resistance (especially in caustic/marine environments), ductility, and crack resistance for demanding chemical, food processing, and industrial applications. It's used in GTAW, GMAW, SAW, and TIG processes for its high-purity nickel deposit, controlling porosity with titanium.
Key Characteristics & Uses:
Composition: High-purity Nickel (Ni) with titanium (Ti) for grain refinement and porosity control.
Applications: Welding pure nickel (Ni 200/201), dissimilar joints (nickel to steel), & steel cladding.
Industries: Chemical plants, food processing, marine, caustic handling, power tools, batteries.
Properties: Excellent corrosion resistance (acids, alkalis, halides), high ductility, good high-temp strength, stable arc.
Welding: Ideal for TIG (GTAW), MIG (GMAW), Submerged Arc (SAW).
Common Applications:
Pumps, valves, and piping in corrosive chemical environments.
Food processing equipment.
Cryogenic applications.
Overlays on steel for corrosion protection in marine or caustic service.
