What is ERNi-1 Welding Wire?
ERNi-1 Welding Wire is a high-purity nickel filler metal classified under the AWS A5.14 specification. It is designed specifically for the welding of wrought or cast forms of commercially pure nickel, such as Nickel 200 (UNS N02200) and Nickel 201 (UNS N02201). This wire typically contains a minimum of 93% nickel and includes controlled additions of titanium and aluminum.
As a leading ERNi-1 welding wire manufacturer, Sankalp Alloys ensures that our product meets stringent quality standards required by fabricators in the USA. The presence of titanium in ERNi-1 is crucial as it acts as a deoxidizer, helping to suppress porosity during the welding process—a common challenge when welding pure nickel.
Why Use ERNi-1 for Nickel 200 and Nickel 201?
Choosing the right filler metal is critical for maintaining the corrosion resistance and mechanical integrity of the base metal. ERNi-1 is the preferred choice for Nickel 200 and 201 for several reasons:
- Porosity Control: Pure nickel is susceptible to porosity from nitrogen and oxygen in the atmosphere. The titanium content in ERNi-1 reacts with these gases to form stable compounds, ensuring a sound, defect-free weld.
- Corrosion Resistance: It matches the exceptional corrosion resistance of Nickel 200/201, particularly in caustic soda (sodium hydroxide) and other alkaline environments.
- Compatibility: It is suitable for joining nickel to itself or to dissimilar metals like carbon steel, making it versatile for various fabrication needs in the USA.
Applications of ERNi-1 Welding Wire
Our ERNi-1 welding wire exporter to USA service caters to a wide range of critical applications where material purity and weld integrity are paramount:
- Caustic Handling Equipment: Storage tanks, evaporators, and transfer piping for sodium hydroxide.
- Chemical Processing: Reactors and vessels involved in the production of synthetic fibers like viscose rayon.
- Food Processing: Equipment for handling fatty acids and fruit juices where contamination must be avoided.
- Dissimilar Welding: Overlaying nickel on steel surfaces to provide a corrosion-resistant barrier.

Frequently Asked Questions (FAQ)
1. What is the difference between ERNi-1 and Nickel 200?
Nickel 200 is the base metal grade (UNS N02200), while ERNi-1 is the welding wire (filler metal) designed to weld it. ERNi-1 contains added titanium to prevent porosity during welding, which Nickel 200 base metal typically does not have in the same quantity.
2. Can I use ERNi-1 to weld steel to nickel?
Yes, ERNi-1 is often used for dissimilar welding applications, such as joining Nickel 200 or 201 to carbon steel, or for overlaying steel with a nickel layer.
3. Do you provide Mill Test Certificates?
Absolutely. All our shipments to the USA are accompanied by a Mill Test Certificate (MTC) in accordance with EN 10204 3.1, verifying the chemical and mechanical properties of the wire.
4. What is the lead time for shipping to the USA?
Lead times vary based on order volume. However, for standard stock items, we typically dispatch within 3-5 days. Sea freight to the USA generally takes 30-45 days, while air freight options are available for urgent requirements.
