Fibre Laser Welding Systems

Fibre laser welding systems are industrial tools that utilize fibre laser technology for the precision welding of metals and other materials. These systems have become increasingly popular in various manufacturing sectors due to their high efficiency, low maintenance, and ability to produce fine welds with minimal heat distortion.

Overview

Fibre lasers use an optical fibre doped with rare-earth elements such as ytterbium to generate a high-intensity laser beam. Unlike traditional lasers, fibre lasers offer superior beam quality, making them ideal for applications requiring high precision, such as welding, cutting, engraving, and marking.

Working Principle

In fibre laser welding, the laser beam is transmitted through a flexible optical fibre to the workpiece. The high energy density of the beam melts the material at the joint interface, enabling the formation of a strong, localized weld. Depending on the application, fibre lasers can operate in continuous wave (CW) or pulsed modes.

Applications

Fibre laser welding systems are widely used across multiple industries, including:

• Automotive: Welding of body panels, exhaust systems, and structural components.
• Electronics: Precision welding of connectors, sensors, and micro-components.
• Medical: Manufacture of surgical instruments and implants.
• Aerospace: Lightweight metal welding in aircraft components.
• Jewelry and Watchmaking: Micro-welding of fine and delicate parts.
• Tool and Mold Making: Repair and fabrication of metal tools.

Advantages

Fibre laser welding offers several benefits over traditional welding methods such as TIG, MIG, or CO₂ laser welding:

Feature	Fibre Laser Welding
Precision	High beam quality for narrow, clean seams
Speed	Faster welding rates
Heat Input	Low heat input with minimal distortion
Maintenance	Fewer moving parts and lower upkeep costs
Material Compatibility	Effective on reflective and conductive metals
Automation	Easily integrated with robotic systems

Technical Specifications

While specifications vary by manufacturer and model, typical parameters for industrial fibre laser welding systems include:

• Laser Power: 100 W to 2000 W
• Wavelength: ~1070 nm (near-infrared)
• Beam Quality (M²): <1.2
• Operating Modes: Continuous wave (CW) and pulsed
• Cooling Method: Air-cooled or water-cooled
• Fibre Delivery Length: Up to 10 meters or more

Why SIRIUS FIBRE is a Smarter Choice

✔️ Built for Precision & Flexibility
SIRIUS offers pulse and continuous modes, high beam quality, and a modular design for workstation or full automation.

✔️ Industrial Power in a Compact Design
Compared to large industrial cells like Trumpf’s, SIRIUS offers similar laser quality in a smaller, more cost-effective setup.

✔️ Affordable German Engineering
Unlike more expensive brands, SIRIUS FIBRE balances performance, durability, and price — making it a smart investment for growing manufacturers.

✔️ Ready for Automation or Manual Use
Unlike handheld-only systems, SIRIUS integrates seamlessly with robotic arms, CNC, or turntables for automated production.

Conclusion

If you’re seeking a high-quality fibre laser welding solution with industrial performance, modern controls, and strong ROI — the SIRIUS FIBRE 300–450 W system is a versatile and reliable alternative to more expensive, less flexible platforms.

Seamless Integration with Sigomatic Software

Advanced Control for Laser Welding Automation

The SIRIUS FIBRE (300–450 W) system is designed for intelligent integration with Sigomatic Software, Sigma Laser’s proprietary control platform. This combination offers a powerful, flexible, and user-friendly environment for managing all aspects of fibre laser welding — from simple weld patterns to fully automated robotic workflows.

What is Sigomatic?

Sigomatic is an industrial laser control software suite developed by Sigma Laser. It provides intuitive interfaces, real-time monitoring, and precise control of laser parameters and motion systems. Built for modularity and scalability, it enables integration of the SIRIUS FIBRE system into both manual workstations and fully automated production cells.

• Vision Systems: Cognex, Keyence, Basler
• Communication Protocols: EtherCAT, Profinet, Modbus, OPC UA

Example Use Case: Automated Welding Cell

Scenario: A customer integrates SIRIUS FIBRE with a 4-axis CNC table and KUKA robot.
With Sigomatic, the system:

• Imports DXF weld path
• Automatically aligns the part using a camera
• Synchronizes motion and laser firing
• Logs weld quality metrics and operating data
• Sends status reports to a central MES system

Benefits of Sigomatic Integration

✅ Faster Setup Times — Preconfigured profiles and intuitive UI
✅ Higher Repeatability — Every weld is consistent and documented
✅ Modular Automation — Add axes, robots, or cameras as needed
✅ Global Industry Standards — Compatible with ISO, CE, and Industry 4.0 systems
✅ Custom Macros & Scripting — For advanced users needing full process control

SIRIUS FIBRE Laser Welding System

Operator User Guide & FAQ

Getting Started

1. Power On the System

• Ensure the cooling system is running (water chiller on).
• Turn on the main power switch.
• Press the start button on the touchscreen panel.

2. Loading a Welding Program

• On the touchscreen, select “Job Management”.
• Choose the welding recipe assigned for your part.
• Confirm parameters (power, speed, pulse mode) if prompted.

3. Prepare the Workpiece

• Place the part securely on the fixture or robot holder.
• Make sure the welding area is clean and free of debris.

4. Start Welding

• Press “Start” on the touchscreen to begin the welding cycle.
• Monitor the weld area if accessible or watch the camera feed if installed.

Common Operator Tasks

How do I pause or stop the welding?

• Press the “Pause” button on the control panel to pause.
• Press “Stop” to halt the process completely.

How to adjust laser power or welding speed?

• Only authorized personnel should change these settings.
• If allowed, go to “Parameter Settings” on the touchscreen, adjust values, and save.

What if the system shows an error?

• Read the error message on screen.
• Common fixes: check cooling, ensure fiber cable is connected, verify workpiece position.
• If unresolved, contact maintenance.

Daily Maintenance Checks

• Check that cooling water temperature and flow are within safe limits.
• Clean the laser head lens gently with a lint-free cloth if dusty.
• Inspect fiber cables for damage or sharp bends.
• Keep the workspace tidy and free from flammable materials.

Safety Tips

• Always wear approved laser safety goggles when the system is in operation (unless fully enclosed).
• Do not bypass safety interlocks or protective covers.
• Never look directly at the laser beam or reflective surfaces.
• Report any unusual noises, smells, or alarms immediately.

FAQ

Q: Can I run different welding jobs one after another?
A: Yes, load the desired program via Job Management before starting each run.

Q: How long can I run the system continuously?
A: The system is designed for industrial use and can run continuously if cooling and safety checks are maintained.

Q: What metals can I weld?
A: Common metals include stainless steel, aluminum, copper, titanium, and similar alloys.

Q: Who should I contact for technical support?
A: Contact your site maintenance or Sigma Laser support using the phone/email provided during training.

Q: How do I shut down the system safely?
