Technology

ERNiCrMo-13 is specifically designed for TIG and MIG welding, utilizing non-consumable tungsten electrodes or continuous wire feeding in MIG welding. The alloy composition provides excellent strength, corrosion resistance, and oxidation resistance for welding high-performance nickel-based alloys and other similar materials.

• Tungsten Inert Gas (TIG) Welding: Uses a non-consumable tungsten electrode to produce an arc that melts the base material and the ERNiCrMo-13 rod to create the weld. This process results in highly precise and clean welds, especially on thin-walled materials.

• Metal Inert Gas (MIG) Welding: Uses a continuous feed of the ERNiCrMo-13 wire into the molten weld pool to create a strong and clean weld. MIG welding is well-suited for high-speed welding of thicker materials.

Theory

During the welding process, the ERNiCrMo-13 rod is melted and fused with the base material. The chromium content helps form a protective oxide layer, while the molybdenum enhances the alloy’s resistance to both oxidation and sulfur corrosion. The nickel content contributes to improved ductility, and the rod’s ability to form a strong, high-quality bond ensures durability in high-stress and high-temperature environments.

The flux coating is formulated to reduce hydrogen exposure during welding, preventing the formation of cracks and ensuring a smooth and clean weld.
