Improvement of quality and efficiency in laser welding for e-mobility.
Improvement of quality and efficiency through flexible beam shaping!
High-quality laser welding of copper and aluminum is essential for e-mobility applications. Despite the challenges posed by these highly reflective and thermally conductive materials, achieving precise welding results is crucial for optimal conductivity and stable circuits. In collaboration with Cailabs, we provide innovative beam shaping solutions that enhance laser interaction with these materials. By using beam shaping technology, the laser output is divided into points and rings, allowing for an even distribution of laser output. Due to the low thermal load, the seams become more homogeneous, and the amount of spatter is significantly reduced. This system is easy to implement, as all optical components are integrated, ensuring long-term stability, reliability, and maintenance-free operation. All components enable the use of high laser output through a fully reflective design and optimized cooling, guaranteeing a stable process. Additionally, an online quality management system can also be integrated.
