Publish Time: 2025-04-24
In the machinery manufacturing industry, specific engineering projects often have unique and stringent requirements for customization of various mechanical parts. Especially when it comes to key components such as rollers, how to improve their surface hardness, wear resistance, corrosion resistance, high temperature resistance, and prevent non-stick steel phenomenon has become the key to improving the service life of workpieces and reducing replacement costs. Surface laser cladding and submerged arc welding processes, as two advanced surface treatment technologies, are gradually becoming effective means to meet these specific needs.
Surface laser cladding technology is a method of using a high-energy laser beam to form a molten pool on the roller surface, and simultaneously feeding an alloy powder of a predetermined composition to melt and solidify it rapidly with the roller matrix, thereby forming a cladding layer with high hardness, wear resistance, corrosion resistance and high temperature resistance. This technology can accurately control the thickness, composition and shape of the cladding layer to ensure that the surface performance of the roller is significantly improved.
Improve hardness and wear resistance: By selecting suitable alloy powders, the laser cladding layer can have extremely high hardness and wear resistance, effectively resist the wear of the roller during operation, and extend its service life.
Enhance corrosion resistance: The laser cladding layer can form a dense alloy structure, effectively isolate the erosion of external corrosive media, and improve the corrosion resistance of the roller.
High temperature resistance: Certain specific alloy powders can maintain stable performance in high temperature environments, making the laser cladding layer have excellent high temperature resistance and suitable for high temperature working environments.
Prevent non-stick steel phenomenon: The laser cladding layer forms a metallurgical bond with the roller substrate, ensuring the firm adhesion of the cladding layer and effectively preventing the occurrence of non-stick steel phenomenon.
2. Submerged arc welding process: Efficiently enhance the surface performance of the roller
Submerged arc welding is a method of welding by burning an arc under a flux layer. Its inherent advantages of stable welding quality, high productivity, no arc light and less smoke make it an efficient means to enhance the surface performance of the roller.
Improve hardness and wear resistance: By selecting suitable welding wire and flux, submerged arc welding can form a cladding layer with high hardness and wear resistance on the roller surface, which effectively resists wear.
Enhance corrosion resistance: The submerged arc welding cladding layer can form a dense metal structure and improve the corrosion resistance of the roller. At the same time, the selection of flux can further enhance the corrosion resistance of the cladding layer.
High temperature resistance: Certain specific welding wire and flux combinations can maintain stable performance in high temperature environments, making the submerged arc welding cladding layer have excellent high temperature resistance.
Process stability: The submerged arc welding process is stable, the welding quality is easy to control, and the uniformity and consistency of the roller surface performance can be ensured.
3. Customization of various mechanical parts: Meet the needs of specific engineering projects
In the process of customization of various mechanical parts, it is crucial to select the appropriate surface treatment technology according to the needs of specific engineering projects. For engineering projects that require high-precision and high-performance rollers, surface laser cladding technology is undoubtedly the first choice. It can accurately control the performance of the cladding layer to meet the stringent requirements for the roller surface hardness, wear resistance, corrosion resistance and high temperature resistance. For engineering projects that require large-scale and efficient production, the submerged arc welding process is more advantageous. It can provide stable welding quality with high production efficiency, ensuring the consistency and reliability of the roller surface performance.
Through customization of various mechanical parts, combined with surface laser cladding or submerged arc welding process, the performance of key components such as rollers can be effectively improved to meet the unique needs of specific engineering projects. This not only increases the service life of the workpiece and reduces the replacement cost, but also provides a strong guarantee for the successful implementation of the engineering project.
