ENiCrMo-3 vs ERNiCrMo-3: What Is the Difference?
ENiCrMo-3 and ERNiCrMo-3 are different filler-metal product forms. They should not be treated as interchangeable simply because both names contain NiCrMo-3.
| Comparison item | ENiCrMo-3 | ERNiCrMo-3 |
| Product form | Flux-covered stick electrode | Bare solid welding wire or TIG rod |
| Main welding process | SMAW / MMA | GTAW, GMAW or SAW, depending on product form |
| AWS specification | AWS A5.11/A5.11M | AWS A5.14/A5.14M |
| Shielding method | Flux-covered electrode; external shielding gas is normally not required | Shielding gas or submerged-arc flux is selected according to the process |
| Product on this page | Yes | No |
ENiCrMo-3 vs ENiCrMo-4 vs ENiCrFe-3 Welding Rods
| Product | Main positioning | Typical application | Selection guidance |
| ENiCrMo-3 ENi625 | Nickel-chromium-molybdenum covered electrode | Alloy 625, compatible Ni-Cr-Mo alloys and selected dissimilar joints | Select when ENiCrMo-3 is specified by the material combination, service requirements or approved WPS. |
| ENiCrMo-4 nickel welding rod | Nickel-chromium-molybdenum covered electrode for a different alloy system | Corrosion-resistant alloy equipment and specified nickel-alloy joints | Select only when the base metal, service condition or approved WPS specifically requires ENiCrMo-4. It is not a universal upgrade from ENiCrMo-3. |
| ENiCrFe-3 nickel welding rod | Nickel-chromium-iron covered electrode | Compatible nickel alloys and selected dissimilar-metal joints | Select when the welding procedure specifically requires a nickel-chromium-iron electrode classification. |

Welding Guidance for ENiCrMo-3 Nickel Alloy Electrode
Welding parameters should be selected according to the base-metal grade, joint design, material thickness, welding position and approved WPS. For corrosion-resistant alloy welding, joint cleanliness, controlled heat input and suitable interpass temperature are important to weld quality.
Use DC+ / DCEP polarity and begin within the applicable reference-current range.
Remove oil, moisture, paint, oxide scale and other contamination before welding.
Use controlled heat input and avoid unnecessarily wide weaving.
Keep electrodes dry and protected from moisture before use.
Follow the Minghua packaging label or product TDS for storage and redrying instructions; do not apply a generic rebaking temperature without confirmation.
Confirm final parameters, preheat and interpass-temperature requirements through the applicable project WPS.
FAQ About ENiCrMo-3 ENi625 Nickel Welding Rod
What AWS specification covers ENiCrMo-3?
ENiCrMo-3 is a covered-electrode classification under AWS A5.11/A5.11M. Buyers should confirm the supplied product classification through the applicable Minghua TDS or certificate of conformity.
What is ENiCrMo-3 ENi625 nickel welding rod used for?
It is used for qualified Alloy 625, compatible nickel-alloy and selected dissimilar-metal joints that require corrosion resistance, crack resistance and elevated-temperature performance.
Can ENiCrMo-3 be used for Alloy 625 welding?
ENiCrMo-3 is commonly associated with Alloy 625 welding. Final suitability must be confirmed against the base-metal specification, service condition and approved WPS.
Is ENiCrMo-3 the same as ERNiCrMo-3?
No. ENiCrMo-3 is a covered stick electrode for SMAW/MMA, while ERNiCrMo-3 is supplied as bare wire or rod for processes such as TIG, MIG or submerged arc welding.
What polarity and current should be used?
Minghua lists DC+ / DCEP polarity. As a reference, a 3.2 mm electrode uses 70–100A and a 4.0 mm electrode uses 100–140A. Final settings depend on the welding position, joint design and approved WPS.
Does ENiCrMo-3 require shielding gas?
ENiCrMo-3 is a flux-covered SMAW electrode and normally does not require an external shielding-gas supply. ERNiCrMo-3 wire used for TIG or MIG is a different product and requires an appropriate shielding system.
Can it weld nickel alloy to stainless steel or low-alloy steel?
It may be used for selected dissimilar-metal joints, but suitability cannot be determined by the electrode name alone. The base metals, dilution, service temperature, corrosion environment and project WPS must be evaluated.
What information is needed for a quotation?
Please provide the required classification, electrode diameter, quantity, packaging, destination, application and certificate requirements. Base-metal grades and the applicable welding procedure are also helpful for product confirmation.
