[0002] In the production of new energy vehicles, high-energy-density laser beams are used to rapidly achieve welding. This minimizes the heat-affected zone (HAZ) while reducing thermal damage to heat-sensitive components such as battery electrodes and preventing degradation of material properties. Localized heating can also effectively control weld deformation, speeding up the assembly of vehicle and powertrain components and enhancing the overall sealing and structural rigidity of the vehicle, making it an excellent method for welding new energy vehicle parts. After the laser parameters are finely adjusted and stabilized, the operator needs to support the laser gun with their elbows to reduce workpiece vibration. Scanning welding is then performed using spiral or sinusoidal scanning paths. During the operation, segmented welding is required to reduce heat accumulation and deformation, making the process highly dependent on the operator's experience.
