Welding Battery Machine: OEM & Customization

Klear Laser customizes the chassis of our battery welding machines to fit production line requirements. Each chassis is engineered for stability and precision alignment during high-speed operations. We use industrial-grade aluminum and steel frames that dampen vibrations and support continuous operation. Custom dimensions and modular designs allow integration into existing automation systems.

Software customization enables seamless control over welding parameters such as pulse frequency, travel speed, and wobble patterns. Our systems run on proprietary firmware with real-time monitoring and error diagnostics. Users can create welding presets for different battery types, including cylindrical, pouch, and prismatic cells. Remote updates and IoT connectivity ensure long-term adaptability.

Laser power is tailored based on application needs, ranging from 500W to 3kW using JPT or Raycus fiber laser sources. Higher power allows deeper penetration for busbar welding, while lower settings suit thin-tab connections without burn-through. The integration of wobble welding heads improves gap bridging and reduces porosity in the weld seam.

Our approach replaces outdated techniques with a scalable, energy-efficient solution built for modern battery manufacturing.

Key Features & Advantages

Klear Laser integrates high-performance JPT or Raycus fiber laser sources across all battery welding systems. These sources deliver unmatched pulse stability and power consistency for delicate battery tab welding. They ensure minimal thermal input while achieving deep, repeatable welds.

The proprietary wobble welding head dynamically adjusts frequency and diameter during operation. This prevents spatter and porosity in battery cell welds. It also ensures uniform bonding without damaging adjacent components.

Precise penetration control up to 5mm ensures strong, hermetic seals in EV battery modules. The beam quality M² <1.2 guarantees micron-scale accuracy. This eliminates defects common in traditional welding methods.

Industrial Applications

Every lithium-ion module that drives an EV starts as a stack of ultra-thin foils that must be joined without adding weight or heat. Klear fiber laser welding machines give automotive OEMs the speed and repeatability they need to tab-weld hundreds of cells per minute while keeping HAZ below 30 µm to protect the separator. The same 1 µm wavelength source is used to seam-weld aluminum housings for prismatic and blade packs, creating hermetic seals that pass IP67 and nail-penetration tests.

In aerospace, the stakes are higher: a single void in a bus-bar weld can arc at 35 000 ft. Klear systems use a wobble welding head with 3 mm amplitude to melt 1.2 mm copper tabs in a controlled keyhole, delivering 100 % penetration with under 0.05 mm sag. The closed-loop encoder tracks every joint so that AS9100 traceability is baked into the process map, not added later by QA.

Marine pack builders fight salt fog and vibration. They switch the laser to pulse mode to stitch-weld 0.8 mm 5083 aluminum battery trays; the rapid solidification refines the grain size and raises salt-spray life from 500 h to 2 000 h compared with MIG. Because the heat input is one-tenth of TIG, the tray stays flat, eliminating post-weld machining of the O-ring groove.
