Designed for giga-factory scale production, PowerWeld-System delivers 24/7 operational reliability with zero-defect quality assurance through multi-layer inspection and full MES traceability. Deployed across Tier 1 suppliers and major OEMs, this system achieves 40-60% throughput improvements while maintaining IATF 16949 automotive quality standards.

Integrated Multi-Process Welding Architecture

Complete EV Battery Welding Matrix:
CELL LEVEL: Tab-to-terminal (8-12μm foil), cell-to-busbar
MODULE LEVEL: Cell-to-frame, busbar networks, cooling plate integration  
PACK LEVEL: Module-to-pack, structural frame, high-voltage interconnects

Three independent laser sources within a single enclosure enable seamless process transitions:

LASER SOURCE 1: 500W precision fiber (tab/foil welding)
LASER SOURCE 2: 3000W high-power fiber (busbar/module)  
LASER SOURCE 3: 100W green laser (copper foil specialty)

Centralized HMI orchestration manages all subsystems through a single interface, reducing operator training from weeks to days.
