Battery Terminal Pole Welding · Fiber Laser

Battery Terminal Laser Welding Machine

The rapid growth of lithium-ion battery manufacturing has created demand for welding systems specifically engineered for battery terminal and pole connections. The Battery Terminal Laser Welding Machine from Shandong Xinhong CNC is purpose-built for welding cylindrical, prismatic, and pouch battery cell terminals to busbars and interconnects. With a 1500W fiber laser source, vision-based positioning, and pulse control optimized for thin foil and tab materials, it delivers consistent, low-resistance welds on aluminum and copper battery terminals at production speeds.

Buyer Pain Points & Solutions

Inconsistent weld quality on thin battery tabs: Battery terminal foils and tabs (0.3-1.0mm) are challenging to weld consistently with resistance welding. The fiber laser's precise pulse control produces repeatable welds without burn-through on thin aluminum and copper tabs.

High-resistance weld joints: Poor weld quality increases joint resistance, reducing battery pack efficiency and creating thermal hotspots. The laser produces full-penetration welds with low and consistent electrical resistance across the cell connection.

Production throughput limitations: Manual or resistance welding is too slow for high-volume battery pack assembly. The automated laser welding system processes up to 360 cells per hour with vision-based automatic positioning.

Core Advantages

Vision-based cell positioning - A camera system identifies battery terminal positions and automatically aligns the laser beam, compensating for cell-to-cell placement variation in the tray. No manual alignment required for each cell.

Pulse control optimized for battery materials - Pulse shape, duration, and frequency are pre-configured for aluminum tabs, copper terminals, and dissimilar Al-Cu welds. The system stores 50+ weld parameter sets for different cell types and tab thicknesses.

Gantry-mounted scanning head - The XY gantry with galvo scanner covers the full battery tray area, welding all terminal connections in a single automated cycle without repositioning the tray.

Low heat input for battery safety - The laser's concentrated energy minimizes heat transfer to the cell, preventing thermal damage to the battery's internal structure. Pulse duration is controlled to keep the heat-affected zone under 0.3mm.

Schneider Electric CNC with production data logging - Modicon M241 PLC logs weld parameters and quality data for every cell, supporting battery pack traceability and PPAP documentation requirements.

FAQ

What battery cell types can this machine weld?

The system welds cylindrical (18650, 21700, 26650), prismatic, and pouch cell terminals. The vision system auto-detects terminal positions for each cell type. Parameter profiles for common cell types are pre-loaded; custom profiles can be created for new cell designs.

Can it weld dissimilar materials like aluminum to copper?

Yes. The system includes pre-configured pulse parameters for aluminum-to-copper dissimilar welds, which are common in battery interconnects. The laser's controlled heat input prevents intermetallic compound formation that weakens Al-Cu joints.

What is the minimum tab thickness the machine can handle?

The minimum tab thickness is 0.3mm for aluminum and copper foils. Pulse energy can be reduced to prevent burn-through on thin materials while still achieving full penetration welds.

Does the machine support production traceability?

Yes. The Schneider Electric PLC logs weld parameters (power, duration, position) for every cell, supporting battery pack traceability and PPAP documentation. Data can be exported via Ethernet to factory MES systems.

Is the machine CE certified?

Yes. The machine is CE compliant for European industrial safety standards. Full compliance documentation is provided with every machine.
