Definition
AWS A5.15 ENi-Cl welding rod is a high-quality welding material specially designed for cast iron welding. It is produced in strict accordance with AWS A5.15 standard and plays a key role in cast iron welding and repair work in many industrial fields, providing a guarantee for the reliable connection of various cast iron materials.
Product Features
Excellent welding processability
AWS A5.15 ENi-Cl electrode has excellent welding process performance. The arc burns very stably, and can maintain continuous and uniform energy output during welding, reducing fluctuations during welding. The spatter phenomenon is extremely small, which effectively reduces the workload of cleaning after welding and avoids weld defects caused by spatter. The slag removal process is easy and easy, ensuring a smooth and flat weld surface, greatly improving welding efficiency and quality.
Good adaptability
It has excellent welding adaptability for various cast iron materials, such as common gray cast iron and ductile iron. Whether it is the fine welding of small cast iron parts or the repair welding of large cast iron structural parts, ENi-Cl electrode can perfectly meet the welding needs under different working conditions.
Excellent crack resistance
During the welding process, the weld has a strong resistance to cracks. This is due to its unique formula design, which can effectively reduce the internal stress during welding and reduce the possibility of cracks, providing a strong guarantee for the long-term stability of the welded structure.
Chemical composition
The chemical composition of welding rod is the key factor for its excellent performance. The content of its main component nickel (Ni) is at a high level, and nickel gives the weld good corrosion resistance and crack resistance. At the same time, it also contains appropriate amounts of silicon (Si), manganese (Mn) and other elements. Silicon can effectively deoxidize and improve the purity of weld metal; manganese helps to improve the structure and performance of the weld, and enhance its strength and toughness. The various elements work together to create a welding material with excellent performance.
| Element | C | Mn | S | Si | Ni | Cu | Al | Fe |
|---|---|---|---|---|---|---|---|---|
| Content(wt.%) | ≤ 2.00 | ≤ 2.50 | ≤ 0.03 | ≤ 4.00 | ≥ 85.00 | ≤ 2.50 | ≤ 1.00 | ≤ 8.00 |
Mechanical properties
Strength performance
The weld metal has appropriate strength to withstand the load under general working conditions. In practical applications, it can provide reliable load-bearing capacity for welded structures and ensure the safety and stability of welded parts during normal use.
Toughness and ductility
Good toughness and ductility are the significant characteristics of AWS A5.15 ENi-Cl electrode welds. This makes the weld less likely to break when subjected to dynamic loads or certain deformations, can effectively absorb energy, adapt to various complex working environments, and improve the reliability and durability of welded structures.

How to use
Preparation before welding
- The surface of the weldment must be strictly cleaned to remove impurities such as oil, rust, paint, and dust to prevent these contaminants from entering the weld during welding and affecting the welding quality.
- Appropriate drying treatment should be performed on the AWS A5.15 ENi-Cl welding rod according to the temperature and time required by the product manual to remove moisture from the welding rod and prevent defects such as pores during welding.
Welding process
- Use DC reverse power supply to ensure arc stability and welding quality.
- Choose a suitable welding current, which generally needs to be adjusted according to factors such as the thickness of the weldment and the welding position. Usually, a smaller welding current is used to control the welding heat input and avoid overheating of the weldment.
- When welding, try not to swing the electrode horizontally, and keep the electrode moving at a constant speed and straight line to ensure that the width and quality of the weld are uniform.
- Pay attention to controlling the interlayer temperature to avoid overheating of the weld, which will cause coarse grains and affect mechanical properties.
Post-weld treatment
After welding, the weld is visually inspected to ensure that there are no defects such as pores, cracks, and lack of fusion on the weld surface. If necessary, appropriate subsequent treatments such as grinding and trimming can be performed according to the actual situation.

FAQ
Q: Is AWS A5.15 ENi-Cl electrode suitable for all types of cast iron?
A: Although welding rod has good adaptability to most common cast irons, such as gray cast iron, ductile iron, etc., for some cast irons with special composition or extremely high performance requirements, welding process assessment may be required to determine whether it is suitable.
Q: What are the effects of too much or too little current when welding?
A: Too much current may cause defects such as overheating of the weldment, coarse grains in the weld, and pores, and will also increase the melting speed of the electrode, affecting the welding quality. Too little current may cause problems such as incomplete penetration and poor weld formation, and the welding strength cannot be guaranteed.
Q: What are the requirements for the storage of welding rods?
A:ENi-Cl welding rods should be stored in a dry, well-ventilated environment to avoid moisture. Unused welding rods should be sealed and dried again before the next use to ensure that their performance is not affected.
