Under the development trend of the new energy vehicle industry pursuing safer, lighter, and more efficient, the welding quality of core components directly determines the performance and safety of the vehicle. From the sealing of the battery tray to the strength of the lightweight structure of the body, the traditional welding process is gradually difficult to meet the stringent requirements-large welding deformation, insufficient weld strength, low operating efficiency and other issues have become a bottleneck for manufacturers to improve production capacity and quality. With the advantages of precision, high efficiency and stability, fiber laser welding machine is becoming a key equipment for the manufacture of core components of new energy vehicles, providing a new path for the industry to break through processing problems.
Traditional welding technology often faces multiple limitations in the processing of new energy automobile parts. Taking the battery tray as an example, when arc welding is used, high temperature can easily cause deformation of the metal substrate, which not only affects the accuracy of subsequent assembly, but may also destroy the sealing of the tray, and there is a risk of battery leakage; For lightweight materials such as aluminum alloy and high-strength steel, traditional welding is prone to weld pores and cracks, resulting in parts that are not up to standard in strength and need to be reworked repeatedly. In addition, the operating efficiency of traditional welding is low, making it difficult to match the needs of large-scale production of new energy vehicle manufacturers, and these pain points are the core directions that fiber laser welding machine can accurately solve.
Fiber laser welding machine uses high-energy-density laser beams to achieve precise welding, fundamentally improving welding quality. Unlike the large-area heating of traditional welding, the laser energy of fiber laser welding machine can be concentrated in the welding area, and the heat-affected area is very small, which can effectively reduce the welding deformation of lightweight materials and ensure the dimensional accuracy of battery pallets, body frames and other components. In view of the sealing requirements of new energy vehicle battery pallets, fiber laser welding machine can form continuous and uniform welds to avoid the pores and inclusions of traditional welding, greatly improve the anti-leakage ability of the pallets, and provide a reliable guarantee for battery safety. At the same time, the fiber laser welding machine has a high degree of automation, which can be seamlessly connected with the production line, significantly improving the welding efficiency and meeting the large-scale production needs of manufacturers.
We have been deeply engaged in laser technology for many years, and we have specially optimized the fiber laser welding machine for the manufacturing needs of new energy vehicles. In the welding scenario of battery pallets, our fiber laser welding machine can achieve super-strength welds over the base material, ensuring that the pallets withstand vibration and shock without weld cracking during long-term use; For complex welds with lightweight body structures, fiber laser welding machine is equipped with a high-precision positioning system, which can accurately respond to the needs of multi-angle and special-shaped welds, reducing manual intervention and operating errors. In addition, we have also equipped the fiber laser welding machine with an intelligent monitoring system, which can monitor the parameter changes in the welding process in real time, and give timely warning in the event of abnormalities to avoid the flow of unqualified products into subsequent links and further improve production stability.
For new energy vehicle manufacturers, fiber laser welding machine is not only an equipment to improve welding quality, but also an important support to promote the upgrading of production efficiency and product competitiveness. With the continuous improvement of the requirements of new energy vehicles for core components, the application scenarios of fiber laser welding machine will be further expanded, from battery pallets and body structures to precision welding of motors and electronic control systems. We will continue to take technological innovation as the core to improve the performance and adaptability of fiber laser welding machine, so that more new energy vehicle manufacturers can break through manufacturing bottlenecks, achieve high-quality, high-efficiency and low-cost production goals, and inject impetus into the high-quality development of the new energy vehicle industry.
