• Weldability: The rod provides easy weldability with low spatter and produces smooth, clean welds.

• Durability: ERNiCr-3 offers exceptional service life in high-stress applications, particularly in areas exposed to thermal cycling and chemical corrosion.

• Ductility: The nickel-chromium alloy provides enhanced ductility in the weld metal, helping to maintain weld quality even under stress.

Technology

ERNiCr-3 is designed for TIG welding and MIG welding applications. These processes use a tungsten electrode or a metal electrode to generate an arc between the base material and the welding rod, which melts and fuses the metals together.

• Tungsten Inert Gas (TIG) Welding: The process uses a non-consumable tungsten electrode, with the ERNiCr-3 rod acting as the filler material. It produces highly precise and clean welds, especially on thin-walled materials.

• Metal Inert Gas (MIG) Welding: The rod can also be used for MIG welding where a continuous wire is fed into the welding pool, providing high productivity and clean welds.

The nickel-chromium alloy composition ensures that the final welds provide excellent strength, corrosion resistance, and oxidation resistance. The rod is specifically designed to withstand harsh conditions, making it suitable for applications in which high temperatures and corrosive environments are common.

Theory

In the TIG welding process, the tungsten electrode creates a concentrated arc of heat between itself and the base metal. The ERNiCr-3 welding rod is introduced into the molten pool, where it fuses with the base material, forming a strong and durable bond. The high levels of chromium in the rod help form a protective oxide layer on the weld, preventing oxidation and enhancing corrosion resistance. The nickel content increases the weld's strength and ductility, which are critical in high-stress applications.
