Cast 308 pure nickel cast iron electrode

Introduction of cast 308 pure nickel cast iron electrode

Cast 308 pure nickel cast iron electrode is a kind of high performance welding material, widely used in all kinds of cast iron and cast steel structure welding repair and connection. Its uniqueness lies in the use of pure nickel as the main alloying element, ensuring excellent welding performance and mechanical strength.

Basic composition of 1.

Cast 308 electrode is mainly composed of welding core and coating. The core is the electrode in the welding process, mainly composed of nickel-based alloy. The drug skin contains a variety of minerals and chemicals, which play a role in protection, alloying and arc stabilization during the welding process.

2. performance characteristics

1. Excellent weldability: cast 308 pure nickel cast iron electrode has excellent weldability for cast iron and cast steel, and can be closely combined with the base metal to reduce the occurrence of welding cracks.
2. High mechanical strength: Due to the use of pure nickel as the main alloying element, the weld after welding has high strength and toughness, which can meet the needs of various complex working conditions.
3. Good corrosion resistance: cast 308 electrode has good corrosion resistance and can maintain stable welding performance in a variety of harsh environments.
4. Convenient operation performance: The electrode has good arc striking and stability, the welding process is easy to control, and it is suitable for various welding techniques.

3. scope of application

Cast 308 pure nickel cast iron electrode is widely used in all kinds of cast iron products, cast steel components of the welding repair, connection and manufacturing process. Suitable for welding castings in bridges, construction, ships, heavy machinery and other industries.

4. method of use

Before using the cast 308 electrode, the weld shall be cleaned to remove oil stains, rust, etc. Select the appropriate welding current and follow the normal welding operation. During the welding process, attention should be paid to controlling the heat input to avoid welding defects caused by too large or too small heat.

5. considerations

1. The welding rod should be stored in a dry and ventilated place to avoid moisture.
2. During the welding process, safety protection measures shall be taken to avoid scalding, electric shock, etc.
3. The use of welding rod shall follow the relevant welding process specifications to ensure the welding quality.

In short, cast 308 pure nickel cast iron electrode is a high-performance welding material, with excellent welding performance, high mechanical strength and good corrosion resistance, widely used in all kinds of cast iron and cast steel structure welding repair and connection. During use, pay attention to storage and use methods to ensure welding quality.
