If you are in the welding industry, you have likely heard about AWS Class ENi-Cl. This classification of welding electrode is used for welding low- and medium-carbon steels. But what exactly is this welding electrode? What are its properties, and what are its uses? In this blog post, we will explore these questions and more to give you a complete understanding of AWS Class ENi-Cl.
What is AWS Class ENi-Cl Coated Electrodes ?
AWS Class ENi-Cl welding electrodes are nickel-based alloys used for specialized applications in mild steel welding. They provide excellent corrosion resistance and mechanical properties when compared to standard mild steel filler metals. The alloy’s unique composition of nickel, chromium, silicon, and phosphorus provides a stronger joint with greater stability than traditional welds. Furthermore, these electrodes create a smoother and more consistent bead than many other carbon steel welding rods on the market today. This makes them ideal for construction projects that require strength without compromising either aesthetics or finish quality.
AWS Class ENi-Cl Coated Electrodes Composition
AWS Class ENi-Cl coated rod comprises 99.1% nickel and 0.9% iron. The nickel content makes it an excellent choice for welding steels prone to cracking.
| C | Mn | Si | S | Fe | Ni+ incidental Cobalt | Cu + incidental Silver | AL | Other |
| 2.0 | 2.5 | 4.0 | 0.03 | 8.0 | 85 min | 2.5 | 1.0 | 1.0 |
AWS Class ENi-Cl Coated Electrodes Physical Properties
AWS Class ENi-Cl Coated Electrodes has a diameter range from 2.5mm to 5.0mm and is coated with a special formulation. The coating acts as a shield to protect the electrode from outside elements that can affect the integrity of the welding. This shield provides a smooth arc, stable arc voltage, and minimal spatter.
AWS Class ENi-Cl Coated Electrodes Mechanical Properties
AWS Class ENi-Cl coated rod has excellent mechanical properties, including high tensile strength, flexibility, and toughness. It is a low hydrogen electrode that reduces the risk of cracking and porosity, making it ideal for welding critical structures.

AWS Class ENi-Cl Coated Electrodes Uses
AWS Class ENi-Cl is primarily used for welding low- and medium-carbon, carbon-manganese, and low-alloy steels. It can also be used for welding high-pressure vessels, pipes, and boilers. Additionally, AWS Class ENi-Cl is an excellent choice for repairing cast-iron parts.
AWS Class ENi-Cl Coated Electrodes Heat Treatment
AWS Class ENi-Cl welding electrode is not considered heat-treatable. However, it can be annealed to soften the metal. The annealing process involves heating the metal to a specific temperature, holding it at that temperature for a specific amount, and then allowing it to cool slowly.
AWS Class ENi-Cl Coated Electrodes Corrosion Resistance
AWS Class ENi-Cl coated electrode has excellent corrosion resistance, making it suitable for harsh environments. It is particularly resistant to saltwater corrosion, which makes it ideal for marine applications.
Conclusion
AWS Class ENi-Cl welding electrode is an excellent choice for welding low- and medium-carbon steels due to its high nickel content, mechanical properties, and corrosion resistance. Its composition, physical and mechanical properties, uses, heat treatment, and corrosion resistance make it a versatile and reliable welding electrode. Whether constructing high-pressure vessels or repairing cast-iron parts, AWS Class ENi-Cl is an excellent choice for your welding needs.
