Driven by the dual trends of new energy vehicles and intelligent manufacturing, laser equipment is evolving from an auxiliary processing tool to a core engine of industrial transformation. From precision welding of automotive bodies in white (BIW) to safe cutting of power batteries, laser technology, with its high precision and high efficiency, is redefining the manufacturing process for both vehicles and power batteries, becoming a key force driving the industry’s advancement towards intelligent, lightweight, and high-safety capabilities.
Laser equipment has brought comprehensive process innovation to automotive manufacturing. In the body processing sector, fully automatic laser welding platforms have become the industry standard, boasting welding speeds of up to 12 meters per minute, far exceeding traditional spot welding processes. TRUMPF’s disc lasers, with their high-reflectivity performance, have become the industry gold standard for BIW welding. TRUMPF’s pioneering BrightLine Weld technology effectively addresses the issue of weld spatter. This technological advantage translates into practical benefits: Raysun’s welding system creates deep, narrow welds in door ring processing, resulting in joints stronger than the parent material while minimizing the heat-affected zone, preventing component deformation. More notably, laser technology has driven the development of lightweight vehicles. By optimizing structural design, thinner sheet metal can be welded together, reducing energy consumption while improving safety.
In the field of power battery manufacturing, laser equipment is the lifeline for ensuring product safety and performance. Welding the copper and aluminum components of lithium batteries has long been a pain point in the industry. TRUMPF’s green laser disc laser specifically addresses this challenge, becoming a core solution in the battery welding market segment. Lianying Laser’s UW series laser die-cutting equipment has taken precision and efficiency to new heights. Its integrated die-cutting and sheet-cutting machines achieve burr- and wrinkle-free tab formation, with a slitting accuracy of ±0.2mm and a product yield exceeding 99.8%. To address the dust hazards associated with traditional processes, these equipment are equipped with a multi-stage dust removal system, eliminating the risk of battery short circuits at the source and providing technical support for safe power battery production.
Intelligence and scalability are another dimension in which laser equipment is reshaping the industry. The deep integration of laser technology with robotics and AI has created a highly flexible production system. Six-axis robots equipped with laser equipment can perform complex 3D trajectory processing. By simply changing fixtures, they can quickly switch between models, adapting to the diverse and large-scale demands of the automotive industry. TRUMPF Group has integrated AI into laser manufacturing, automating equipment operations and maintenance through condition monitoring services. One automaker has significantly reduced manual intervention in replacing laser protective lenses. This intelligent upgrade directly drives cost optimization. Hesai Technology has reduced product costs to just under 1,000 yuan through automated LiDAR production processes, driving its adoption across BYD’s entire model line.
From an industrial perspective, laser equipment is witnessing the transformation of China’s manufacturing industry from “import substitution” to “technology leadership.” Since 2025, companies like Han’s Laser and Yifei Laser have secured significant orders, achieving breakthroughs in areas such as power battery processing. Laser technology not only addresses pain points in traditional manufacturing but also creates new industrial value. TRUMPF’s high-speed laser cladding technology applies a wear-resistant coating to brake discs, helping vehicles meet stringent Euro 7 emissions standards. Lianying Laser’s S-shaped die-cutting technology reduces material costs through an integrated process. In the era of new energy and intelligent manufacturing, laser equipment has become a core support for the high-quality development of the automotive and power battery industries. From precision machining on the shop floor to efficiency upgrades across the entire supply chain, laser technology is writing a new chapter in the manufacturing industry, injecting continuous momentum into the automotive industry’s electrification transformation and the safety upgrades of power batteries.
