Large-format QCW laser galvanometer welding machine

This large-format QCW laser galvanometer welding machine handles complex, high-precision welds across oversized components—think battery trays, chassis subassemblies, and structural EV parts up to 1200 × 1200 mm. Unlike conventional systems that rely on moving the workpiece, it keeps parts stationary while steering the laser beam at high speed using precision galvo optics and a dynamic F-theta lens. That means consistent weld geometry across wide areas without repositioning or fixturing compromises.

Operators notice fewer reworks and tighter cycle times right away: the QCW (quasi-continuous wave) fiber laser delivers controlled peak power without overheating thin sections, while the galvo head achieves scanning speeds over 7 m/s—so even intricate seam patterns finish faster than with robotic arm setups. Plus, real-time thermal feedback and adaptive pulse control help maintain uniform penetration depth, even on joints with variable gap or reflectivity.

Every unit rolls off our Shenzhen production line after full functional testing under ISO 9001-certified quality management—and carries CE marking for compliance with EU machinery directives. We build these machines in-house, from optical alignment to software integration, so updates, spares, and technical support stay responsive and grounded in actual field use—not just spec sheets.
