PowerWeld-BM3000: Multi-Spot Laser Welding for EV Battery Modules

The PowerWeld-BM3000 is an industrial-grade laser welding system engineered for high-volume EV battery module manufacturing. With a 3000W fiber laser source and multi-spot beam splitting technology, it delivers consistent, low-resistance welds across battery cell terminals and busbars in a single pass.

Key Features

• 3000W IPG/nLIGHT fiber laser — stable output for 24/7 production
• Multi-spot beam splitter — weld 4–16 spots simultaneously, reducing cycle time by up to 60%
• Automated vision alignment — ±0.05mm positioning accuracy for mixed cell formats
• Compatible cell formats: 18650, 21700, 4680, prismatic, pouch
• Inline weld inspection: real-time monitoring of weld depth, spatter, and resistance
• Nitrogen purge chamber — prevents oxidation on aluminum and copper busbars

Technical Specifications

Applications

Designed for EV battery module assembly lines, the BM3000 is deployed in PACK lines for passenger EVs, commercial vehicles, and energy storage systems (ESS). Compatible with CATL, BYD, and custom module formats.

Why Choose PowerWeld-BM3000?

Traditional resistance welding struggles with the thin foil tabs and tight pitch of modern battery cells. The BM3000's non-contact laser process eliminates electrode wear, reduces heat-affected zones, and achieves weld tensile strength exceeding 98% of base material — critical for battery safety and longevity.
