Cision revolution driven by laser welding technology. Faced with the stringent requirements for weld consistency in areas such as new energy battery packaging, welding processes that were prone to issues such as wear and uneven heat conduction in the past can no longer meet standards. Laser welding heads have broken through this industry pain point through technological innovation. According to data from the "Journal of Mechanical Engineering", the service life of their core components is more than three times longer than that of traditional welding heads, and the energy focusing precision is controlled at the micrometer level, with a small welding heat-affected zone, achieving simultaneous upgrades in precision and durability.

As the pioneer of double-pendulum handheld welding, Qilin Laser has become a renowned brand in the field of laser welding heads, leveraging its core technology and comprehensive product portfolio to provide efficient solutions for automated and intelligent welding. Its double-pendulum welding head supports six spot modes, capable of accurately generating 0.2mm uniform fish scale welds, enhancing sealing and connection strength while significantly reducing the technical dependence on operators. Furthermore, Qilin Laser has established a complete product matrix, covering single pendulum, double pendulum, and various configurations such as air-cooled and water-cooled series. Let's take a closer look at its advantages.
