In lithium laser welding, ensuring quality is critical as it requires precise control over welding depth and width while minimizing deformation and connection gaps. Laser welding provides exceptional results, but process monitoring and quality control are key challenges. Traditional cameras struggle to capture the internal molten pool state during welding due to brightness overexposure. SinceVision's intelligent high-speed camera, combined with specialized light sources or optical paths, overcomes this hurdle. It enables clear observation of laser trajectories, molten pool dynamics, and splashing directions, offering an advanced solution to optimize the lithium welding process.
