Hyfindr Clips - Laser Cutting and Welding of Bipolar Plates explained - Graebener

This Hyfindr Clips we discuss the use of laser technology in the manufacturing process, particularly for cutting and welding metal plates used in energy applications. Laser cutting is crucial for achieving precise shapes, especially in areas with small holes and intricate designs. We highlight the importance of high edge quality in these parts, particularly around ports for hydrogen, air, and water cooling. Laser technology allows for flexibility in shaping, even accommodating complex 3D designs.
After cutting, the next step is welding, where two plates are joined together. Welding requires precise alignment and clamping to ensure a strong bond, especially around edges and ports to maintain leak-tight seals. The welding process is described as critical, requiring expertise not only in laser settings but also in clamping and fixation to achieve stable and high-quality welds.
