Why Choose NS Series Wobble Heads?
Built for robotic, CNC and gantry welding systems, the NS Series combines adjustable X–Y beam oscillation, integrated control and water-cooled optics in a compact welding head.
X–Y Dual-Galvo Control
Two motor-driven galvo axes create adjustable beam trajectories for wider weld seams and improved joint tolerance.
Adjustable Wobble Parameters
Select multiple patterns and adjust the wobble size from 0.1–5 mm and frequency from 0–300 Hz.
Integrated Touchscreen Control
Set the pattern, size, frequency and origin compensation directly from the integrated control interface.
Water-Cooled Architecture
Dedicated water cooling protects the optical path and helps stabilize the head during continuous welding.
Service-Friendly Optics
An enclosed optical path and drawer-type protective lens simplify routine inspection and replacement.
QBH-Based Integration
Designed for compatible fiber laser sources using a QBH connection. Final configuration is confirmed before order.
Adjustable Wobble Patterns and Touchscreen Control
The built-in control interface allows operators and system integrators to adjust the beam trajectory without an external computer.
Available adjustments include:
- Multiple preset beam trajectories
- 0.1–5 mm adjustable wobble size
- 0–300 Hz adjustable frequency
- X/Y trajectory ratio
- Wobble origin compensation
- Chinese and English interface options
These adjustments make it easier to develop welding settings for butt, lap, fillet and sealing welds. Final parameters still depend on the material, thickness, joint design, shielding gas and welding speed.
Integrated Design for Automated Laser Welding
Integrated controls, water-cooled optics and service-friendly components help simplify installation and routine maintenance in robotic, CNC and gantry welding systems.
Integrated controls reduce installation complexity. The control board, galvo drivers and X–Y motor modules are built into the welding head, helping reduce external wiring and save space in automated welding equipment.
- Integrated control board and galvo drivers
- On-head touchscreen parameter adjustment
- Water-cooled optical path and head structure
- Optional CCD, process gas and side air knife configurations
Routine protective-lens access is designed to be faster. The drawer-type lens assembly can be removed for inspection, cleaning or replacement without dismantling the complete optical head.
- Two locking screws secure the protective-lens drawer
- Quick access for inspection and replacement
- Protective lens helps isolate the focusing optics
- Simplified routine maintenance procedure

Application feasibility and welding parameters should be confirmed using the material, thickness, joint geometry, required penetration and target cycle time.
Confirm Compatibility Before Ordering
Because fiber laser sources and automation platforms can use different optical and mechanical configurations, please provide the following information with your inquiry:
- Fiber laser brand, model and power
- Fiber connector and core diameter, if known
- Material and material thickness
- Joint type and required weld width
- Robot, CNC or gantry platform
- Required working distance
- CCD viewing or side air knife requirement
- Required focal-length configuration
Our engineers will recommend the appropriate welding head and confirm the final optical and mounting configuration.

Frequently Asked Questions
Is the NS Series a complete laser welding machine?
No. The NS Series is a welding head designed for system integration. A compatible fiber laser source, water chiller, robot or motion platform, control and safety system, and shielding-gas setup are required.
How do I choose between the 3kW, 4kW, 6kW and 8kW models?
Start with the fiber laser power, material, thickness, joint type, required penetration and working distance. We will then confirm the appropriate head and optical configuration.
Which fiber laser sources are compatible?
The NS Series uses QBH-based configurations, but compatibility also depends on the power, wavelength, connector, fiber core and selected optics. Please provide the laser source model before ordering.
What parameters can be adjusted from the touchscreen?
Depending on the model, the interface can adjust the wobble pattern, wobble size, frequency, X/Y ratio and origin compensation.
Is water cooling required?
Yes. The welding heads use water cooling for the optical components and/or head body. Chiller flow, pressure, temperature and port arrangement should be confirmed for the selected model.
Are CCD viewing and side air knives available?
CCD viewing, coaxial gas protection and side air knives are available on selected configurations. Please confirm whether they are standard or optional for the required model.
