AWS Class ERNi-1 MIG and TIG filler welding wires and rods are primarily used for welding pure nickel and nickel-based materials. They are widely applied in chemical processing equipment, caustic soda plants, food and pharmaceutical processing units, and heat-resistant components. These fillers are also suitable for surfacing and repair welding where corrosion resistance and metallurgical compatibility are essential. Due to their excellent ductility and resistance to cracking, ERNi-1 welding wires and rods are ideal for precision TIG welding and controlled MIG welding applications requiring clean, sound, and durable welds.
