2021 is China's new energy vehicle industry market "first year", in a series of favorable factors driven by China's new energy vehicle industry, the rapid development. Statistics show that in 2021, the production and sales of new energy vehicles will reach 3.545 million units and 3.521 million units respectively, 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%. GGII expects that by 2025, the market size of China's lithium equipment is expected to reach 57.5 billion yuan. Lithium battery module and PACK equipment market is also expected to benefit from the rapid growth of the scale.
Laser welding equipment is currently used in the new energy industry in the following areas, respectively, the front section of the explosion-proof valve laser welding, pole laser welding, connection piece laser welding; the middle section of the sealing welding, sealing stare laser welding; the rear section of the bus laser welding and detection line laser welding.
The following is a brief introduction to the advantages of several laser welding equipment applications in the new energy industry.
- Laser welding equipment explosion-proof valve welding using fiber laser can effectively improve the welding quality and welding yield, configured with special welding head, adjustable spot size, can meet the requirements of different welding processes to ensure the welding effect and stability.
- Laser welding equipment in the pole welding fiber + semiconductor composite welding process, can effectively suppress welding spatter to reduce welding fry point, improve welding quality and ensure welding yield. Equipped with high-precision pressure sensor, real-time detection of pole column pressure, to ensure stable seal compression, while detecting insufficient gas source pressure alarm prompt.
- Laser welding equipment in the CCS nickel sheet laser welding using IPG fiber laser, the most successful laser brand, its stability, penetration, low attenuation and high energy utilization is not comparable to other brands. In the welding of CCS nickel sheet, it is popular among customers for its high welding rate, fast speed, beautiful weld joints and operability.
