Products Description

Nickel-based welding wire has important applications in welding nuclear power plant equipment. As a key equipment in the special environment of a nuclear power plant, the selection of welding processes and materials is crucial to ensuring the safety and reliability of the equipment.

Nickel-based welding wires offer several advantages in welding nuclear power plant equipment. First of all, nickel-based welding wire has excellent corrosion resistance and can resist corrosive media present in nuclear power plants, such as acid and alkali solutions, high-temperature water vapor, etc. This corrosion resistance can effectively extend the service life of equipment and reduce the frequency of repairs and replacements.

Secondly, nickel-based welding wire has excellent high-temperature strength and thermal stability. Nuclear power plant equipment will be affected by high temperatures and thermal cycles during operation, and nickel-based welding wire can maintain high strength and stability in high-temperature environments and is not prone to deformation and cracks, ensuring the reliability and sealing of welded joints.

In addition, nickel-based welding wire can adapt to thermal expansion and contraction caused by temperature changes in nuclear power plant equipment. It has good thermal expansion properties and can effectively absorb thermal stress and reduce stress concentration on welded joints and equipment structures, thereby reducing the risk of damage and fracture caused by thermal fatigue.

When welding nuclear power plant equipment, it is very important to select the appropriate nickel-based wire material and welding process. Factors such as the working conditions of the equipment, the requirements of the welded joints, and the compatibility of materials need to be considered to ensure the quality of the welding and the reliability of the joints. In addition, strict quality control and welding monitoring are also key measures to ensure welding quality.

Production Process:

The production process of nickel-based welding wire usually includes the following main steps:

Raw material preparation: Select high-purity nickel alloy as the main raw material. Depending on the specific requirements of the welding wire, other alloying elements and additives may be added.

Material pretreatment: Pretreatment of raw materials, including steps such as cleaning, grinding and screening, to remove impurities and ensure the uniformity of the material.

Smelting and alloying: Put the pretreated raw materials into a high-temperature smelting furnace for smelting and alloying. By heating and controlling the amount of alloying elements added, ensure that the alloy composition reaches the required ratio.

Continuous casting or hot rolling: Pour the melted alloy liquid into a continuous casting machine or perform hot rolling to form continuous bars or strips.

Steel wire drawing: The continuously cast bar or hot-rolled strip is subjected to a series of steel wire drawing processes to gradually reduce the diameter to form a welding wire of the required diameter.

Welding wire surface treatment: Surface treatment of the welding wire, including degreasing, pickling and polishing, to remove surface oxides and impurities and improve the surface quality of the welding wire.

Welding wire packaging and storage: Welding wire is packaged. Common packaging forms include boxes, spools, and spools. Welding wire is inspected for quality after packaging and stored in a dry, corrosive gas-free environment to maintain its quality and performance.
