2021 is China's new energy automobile industry market-oriented "first year", driven by a series of favorable factors, China's new energy automobile industry is developing at a high speed. Statistics show that in 2021, the production and sales of new energy vehicles were completed 3.545 million units and 3.521 million units, an increase of 1.6 times year-on-year. It is expected that by 2025, China's new energy vehicle market penetration rate is expected to reach 30%, far exceeding the national target of 20%. New energy vehicle demand increase drive upstream power battery demand increase, indirectly drive the growth of China's lithium battery equipment market size.GGII expects China's lithium equipment market size is expected to reach 57.5 billion yuan by 2025. Lithium module and PACK equipment market is also expected to benefit from the scale of rapid growth.
Laser welding equipment in the new energy industry is mainly used in the following areas, respectively, the front section of the explosion-proof valve laser welding, pole laser welding, connecting piece laser welding; in the middle section of the seal welding, sealing staring laser welding; the rear section of the busbar laser welding and laser welding of the detection line.
The following is a brief introduction to the advantages of several laser welding equipment used in the new energy industry.
- Laser welding equipment explosion-proof valve welding using fiber laser can effectively improve the welding quality and welding yield, configuration of special welding head, spot size adjustable to meet the requirements of different welding processes, to ensure that the welding effect and stability.
- The laser welding equipment adopts fiber optic + semiconductor composite welding process in pole welding, which can effectively inhibit welding spatter and reduce the welding blow point, improve welding quality and ensure welding yield. Equipped with high-precision pressure sensors, real-time detection of column pressure, to ensure stable seal compression, while detecting the gas source pressure is insufficient alarm prompts.
- Laser welding equipment in the CCS nickel laser welding using IPG fiber laser, the most successful laser brand, its stability, penetration, low attenuation and high energy utilization can not be compared with other brands. In the welding of CCS nickel sheet with high penetration rate, fast speed, beautiful weld joints, maneuverability is very popular among customers.
