Laser Welding Scanning System GWM Series | High-Speed, High-Precision Multi-Spot and Seam Welding

Key Takeaways
• Controls laser beam using a galvano scanner without an XY table
• Supports high-speed, high-precision spot and seam welding
• Enables multiple welding conditions within a single workpiece, reducing setup time
• Supports wobble welding to improve heat input control and weld quality

------------------------------------------------------------
AMADA’s laser welding scanning system is designed for welding processes requiring high speed,

precision, and process stability. By combining a galvano scanner with a digital scanning system,
laser beam positions can be freely controlled within the work area without moving the workpiece.

🔷 System Operating Principle
The system scans the laser beam along the X and Y axes using a galvano scanner instead of
mechanical XY table movement. The laser beam is transmitted via optical fiber and controlled by
a high-resolution digital scanner, enabling fast response and reduced mechanical constraints.

🔷 Supported GWM Series
The GWM series can be used in combination with AMADA laser welding machines according to
the laser source type.

🔷 Key Technical Features
Digital drive circuits improve positional repeatability and reduce the effects of thermal drift.
• Maximum repetition rate: 5,000 pps
• Supports seam welding in CW (Continuous Wave) mode
• Maximum processing area: 220 × 220 mm (GWM-STD2)
These features ensure stable welding even in high-precision applications.

🔷 Welding Process Capability
Supports multiple spot welding conditions within a single workpiece, suitable for parts with
different materials or thicknesses.
Also supports wobble welding by scanning the laser beam in a spiral pattern, controlling heat
distribution, reducing crack risk, and improving weld quality.

🔷 Applications
Designed to integrate directly with AMADA laser welding machines, suitable for:
• Multi-point spot welding
• High-speed seam welding in confined spaces
• Welding processes requiring precise laser output control

📘 Summary
The GWM series laser welding scanning system enables X–Y laser beam control without moving
the workpiece using galvano and digital scanners. It supports spot welding, CW seam welding,
and wobble welding within a maximum processing area of 220 × 220 mm (GWM-STD2),
delivering precise and stable welding for production lines.
