Custom lithium battery laser welding equipment manufacturer | Prismatic battery module laser welding automation | Reduce spatter in battery busbar laser welding

Pioneering Safe and Efficient Battery Manufacturing with Hailei Laser

Core Selling Points: Precision, Safety, and Unmatched Stability

• Advanced Spatter Suppression Technology: Spatter is the biggest enemy of battery safety, risking insulation layer damage and internal short circuits. Hailei Laser utilizes high-stability industrial laser sources combined with intelligent power modulation and beam oscillation technology. This precise energy control creates a stable molten pool, suppressing metal vaporization and reducing the spatter rate to below 0.5%. The result is a clean, burr-free weld that significantly lowers post-weld cleaning costs and safety risks.
• High-Precision Gantry Automation for Prismatic Modules: Our gantry structure guarantees high rigidity and smooth, vibration-free movement over large travel distances. Integrated with high-resolution CCD visual positioning systems, the equipment automatically compensates for slight mechanical deviations during the loading of prismatic battery modules. This ensures the laser beam hits the exact center of the busbar every time, achieving consistent penetration depth and a first-pass yield rate exceeding 99%.
• Minimal Heat-Affected Zone (HAZ) Protection: Lithium battery components, such as copper and aluminum busbars, are extremely thin and heat-sensitive. Our customized laser parameters deliver sufficient penetration for a strong metallurgical bond while keeping the HAZ exceptionally small. This prevents thermal damage to the battery cells, protects the internal separator, and avoids excessive internal resistance, thereby preserving the battery's optimal performance.
