Laser welding has proven to be one of the most precise and efficient methods for manufacturing bipolar plates in fuel cells. Due to the high requirements for accuracy and quality in the production of bipolar plates - especially with regard to gas-tight connections and structural integrity - the laser offers significant advantages over conventional welding methods.
Despite the numerous advantages of laser welding in the production of bipolar plates, there are some challenges that need to be taken into account during process control. These challenges are mainly due to the material properties of the bipolar plates and the complexity of the welding task.
The processobserver enables continuous monitoring of key parameters such as laser power, beam position and weld seam quality.
