In recent years, the global new energy vehicle industry has flourished, leading to a sharp increase in the demand for welding of high-reflective materials such as pure copper. Given that copper absorbs blue light much more efficiently than infrared light, blue laser technology has shown significant advantages in welding related materials, offering high precision, high efficiency, and flexibility, thereby providing efficient and high-quality processing solutions.
Addressing Pain Points: Blue Laser Welding Technology Balances Efficiency and Quality
The 'three-electric' system (battery, motor, and electric control) of new energy vehicles, as core components, imposes stringent requirements on welding technology during the manufacturing process. Traditional high-power infrared laser welding often faces issues such as blowholes and spatter when processing highly reflective metals like copper, gold, and aluminum. These problems not only affect the weld quality and appearance but may also contaminate and damage the optical components of the laser. Therefore, efficiently and stably welding highly reflective metal materials has become a pressing challenge in the new energy vehicle industry.
Compared to infrared lasers, blue lasers generate almost no porosity or spatter during welding and cladding processes, ensuring a smooth weld appearance and reducing the need for secondary processing. At the same time, they enable stable welding of pure copper with low-power lasers, making the process energy-efficient and environmentally friendly.
