According to foreign media reports, optical fiber laser welding ('hbar laser welding) has recently made technological advancements to help lightweight and battery manufacturing. Fiber lasers are a reliable and compact energy-saving system that can provide the best beam quality (best beam quality) for applications where precision is important. If the light laser processing technology is adopted, the flange size can be minimized and greatly reduced Body weight. At the same time, optical fiber can be used to achieve bean delivery, which aims to ensure the simplicity of robot technology integration, so as to maximize processing speed and minimize material and operating costs.

The fiber laser welding system is optimized for dissimilar metal joining. This technology has gradually become an important tooling in the electric vehicle market. The fiber laser adopts the swing laser process, and its weld seam is stable and highly uniform, and will not affect the surrounding materials. Currently, the following companies are developing light laser systems for battery welding: Apache fiber laser technology company "IPG Photonics" and German Trumpf company (Trumpf).

Some fiber welding manufacturers are also preparing to enter the automotive lidar market. The wavelength of the fiber laser is 1.5 um visible light, which is far safer than the 905 nm laser diode used in conventional lidar systems. This wavelength allows the new fiber lidar to operate at a higher power, and enhances the detection range of the autonomous driving car lidar. Its resolution is extremely excellent, and its functions are also very comprehensive. It has the worries that other lasers do not have.

Because the technology is based on optical fibers, free-space optical and mechanical components can improve system stability with excellent performance, and its products have a longer monthly lifespan. The Lunhar company in the United States is a fast-growing laser demand start-up company. Volvo made a large investment in the company in 2018. Toyota was the first car company to have a partnership with Lumimar. Started to use fiber lasers to test autonomous driving technology.

It is worth mentioning that IDTechEx predicts that the global fiber laser market will reach 8.9 billion US dollars by 2028.
