In today's rapidly evolving new energy vehicle industry, power batteries serve as the core component, and their manufacturing processes directly determine vehicle safety and driving range. Laser welding technology—thanks to its high efficiency, precision, and low heat input—has become the "golden process" in power battery production. The rational selection of welding methods and processes directly affects battery cost, quality, safety, and consistency. This article provides a comprehensive overview of laser welding for power batteries.
Against the backdrop of accelerated new power system construction, grid operation and maintenance are undergoing a comprehensive upgrade toward live-line, green, intelligent, and low-risk operations. Transmission lines, substation equipment, and new energy station equipment are exposed to harsh outdoor conditions year-round, frequently facing contamination, rust, oxidation, and floating debris entanglement.
