According to reports, fiber laser welding has recently made technological advances to help reduce weight and battery manufacturing. Fiber lasers are a reliable, compact, energy-saving system that delivers the best beam quality for applications where accuracy is critical. If the light green laser pointer process is used, the flange size can be minimized and the weight of the body can be greatly reduced. At the same time, fiber delivery can be achieved using fiber optics to ensure the simplicity of robotic technology integration, maximizing processing speed and minimizing material and operating costs.
The fiber laser welding system is optimized for dissimilar metal joining and has become an important tooling in the electric vehicle market. The fiber laser adopts the oscillating laser process, and the weld seam is stable and highly uniform, and does not affect the surrounding materials. Currently, the following companies are developing light laser systems for battery soldering: IPG Photonics and Trumpf.
Some fiber soldering manufacturers are also preparing to enter the automotive laser radar market. Fiber lasers have a visible light range of 1.5 μm, which is far safer than the 905 nm laser diode used in conventional laser radar systems. This wavelength allows the new fiber laser radar to operate at higher powers, improving the range of exploration of the autonomous vehicle-mounted lidar, its resolution is excellent, and its functions are comprehensive, with advantages not found in other green laser pointers.
Because the technology is based on fiber optics, free-space optics and mechanical components improve system stability and have a long product life. Luminar in the United States is a fast-growing laser radar startup. Volvo made a large investment in the company in June 2018. Toyota is the first car company to establish a partnership with Luminar and will start to use it in 2017. Fiber laser testing of 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.
