2026 Laser Welding Aluminum Technology Innovation: Empowering the Upgrade of New Energy Vehicle Battery Cold Plates

[Industry Dynamics] Under the global "dual carbon" strategy, the booming new energy vehicle (NEV) industry has driven a surge in aluminum demand. As a core component of power battery thermal management systems, battery cold plates place extremely high requirements on the precision and stability of welding processes. The high thermal conductivity and high reflectivity of aluminum make traditional welding processes difficult to adapt to the thin-walled structure and microchannel sealing requirements of cold plates. Laser welding technology, with its advantages of precise temperature control, high efficiency and stability, has become a core solution to this problem, promoting the high-end upgrading of the aluminum processing industry.

Traditional welding processes have significant pain points in cold plate processing: excessive heat input causes weld deformation and damages internal microchannels; the wide heat-affected zone reduces aluminum strength; and low efficiency makes it difficult to match mass production needs. Taking mainstream cold plate processing as an example, traditional processes have high rework rates and costs, becoming a bottleneck for capacity improvement.

Laser welding technology has targeted breakthroughs in cold plate welding pain points, achieving three core advantages: First, precise shape control, with weld deformation ≤ 0.08mm, protecting microchannel structures and ensuring aluminum strength; second, efficiency multiplication, with welding speed increased by more than 6 times compared with traditional processes and energy consumption reduced by 40%; third, high sealing reliability, with welds free of pores and cracks, and leakage rate far lower than industry standards, meeting long-term service requirements.

Currently, laser welding has become a core process for large-scale production of NEV battery cold plates. Enterprises in Germany and China have adopted this technology to realize mass production of cold plates, effectively improving efficiency, reducing costs, and ensuring the reliability of power battery thermal management systems.

Global laser welding equipment enterprises are accelerating technological upgrading. The application of vision guidance, dual-robot collaboration, AI intelligent control and other technologies has further improved welding precision and yield rate, promoting laser welding equipment to become a standard configuration for high-end cold plate processing.
