DIPTI METAL INDUSTRIES
DIPTIINOX® ERNi-1 TIG Rod (AWS A5.14): Leading ERNi-1 Manufacturer, ERNi-1 Exporter, and Bulk ERNi-1 Supplier for Pure Nickel Alloys
Dipti Metal Industries is a Leading ERNi-1 TIG Rod Manufacturer and Pure Nickel Welding Wire ERNi-1 Exporter in Mumbai, India, specializing in high-purity AWS A5.14 ERNi-1 GTAW filler metal under the DIPTIINOX® brand. This filler metal is essential for welding Commercially Pure Nickel grades such as Nickel 200 (UNS N02200) and the low-carbon Nickel 201 (UNS N02201)—materials crucial for exceptional resistance to hot **caustic alkalis** and various reducing acids. As a trusted Nickel Alloy TIG Rod ERNi-1 Supplier, we guarantee full conformance to AWS A5.14 and supply all standard diameters for Gas Tungsten Arc Welding (GTAW) and Gas Metal Arc Welding (GMAW). Our ERNi-1 rods are widely used in the chemical industry, salt production, and for crucial dissimilar metal joining.
DIPTIINOX® ERNi-1: The Filler Metal for Commercially Pure Nickel Fabrication
The AWS A5.14 ERNi-1 TIG Rod is a commercially pure Nickel filler metal containing controlled amounts of Manganese (Mn) and Titanium (Ti). This composition is engineered to control minor impurities and act as a deoxidizer during welding, which is critical for preventing porosity in pure nickel welds. It is the primary filler metal for joining Nickel 200/201 base metals, and its weld deposit maintains the same superior corrosion resistance, particularly against **caustic soda (NaOH)**, as the base material. Dipti Metal Industries ensures every ERNi-1 GTAW Rod is precision-drawn and chemically balanced to deliver stable arc characteristics and high joint strength. We are a reliable Nickel Alloy TIG Rod Exporter providing certified filler metals for critical **chemical processing** and **electronics** applications globally.
