Continuous Wave Fiber Laser Welding Machine

High-Power Continuous Laser Welding for Industrial Metal Manufacturing

The JUYI Continuous Wave Fiber Laser Welding Machine is a high-performance laser welding solution designed for fast, stable, and efficient welding of metal components, sheets, tubes, frames, and industrial assemblies.

Using a high-quality continuous wave fiber laser source with a 1080 nm wavelength, the system provides stable continuous laser output and high beam quality for precise and efficient metal joining. Available in 500W, 800W, 1000W, and 1200W configurations, it can be selected according to different material thicknesses, welding speeds, and production requirements.

With a power adjustment range of 10–100%, water cooling, M² beam quality below 1.3, and long-term output stability, the machine is suitable for both standalone welding and automated industrial production.

How Does a Continuous Wave Fiber Laser Welding Machine Work?

A Continuous Wave (CW) fiber laser welding machine generates a stable laser beam that operates continuously during the welding process.

The laser source generates high-power laser energy, which is transmitted through an optical fiber to the welding head. The focusing optics concentrate the beam into a small area on the workpiece, producing a high energy density that rapidly melts the metal.

As the welding head moves along the joint, the molten metal forms a continuous weld pool and solidifies behind the laser beam to create a strong and consistent weld.

Welding Process

Fiber Laser Source → Fiber Transmission → Beam Focusing → Localized Melting → Continuous Welding → Rapid Solidification

The continuous output makes CW fiber laser welding particularly suitable for long weld seams, high-speed welding, and high-volume production.

Key Advantages

High Welding Speed

Continuous laser output provides a constant energy supply, allowing the welding head to move quickly along the joint.

This makes the system suitable for:

• Sheet metal welding
• Tube and profile welding
• Frame welding
• Long weld seams
• High-volume production

High Beam Quality

The system provides beam quality of M² < 1.3, allowing the laser beam to be focused into a small and concentrated spot.

High beam quality contributes to:

• High energy density
• Precise welding
• Stable weld formation
• Narrow heat-affected zones
• Improved welding consistency

Stable Laser Output

The laser power can be adjusted from 10% to 100%, while power stability is specified at ±2% under the rated operating conditions.

This helps maintain consistent energy delivery and repeatable welding quality during production.

Efficient Heat Input

The concentrated laser beam delivers energy directly to the welding area, reducing unnecessary heat transfer to surrounding material.

This can help minimize:

• Thermal deformation
• Heat-affected zones
• Material distortion
• Post-welding finishing

Long-Term Industrial Operation

The laser system is designed for long operating periods, with the specification indicating power stability of ±2% after more than 100 hours for the 500W model and more than 1100 hours for the higher-power configurations.

This makes the system suitable for continuous industrial production.

Flexible Power Configuration

The series is available in four power levels:

• CT-500: 500W ±15W
• CT-800: 800W ±20W
• CT-1000: 1000W ±20W
• CT-1200: 1200W ±25W

This range allows manufacturers to select a suitable laser power according to material, thickness, welding speed, and production requirements.

High-Efficiency Water-Cooled System

All listed models use water cooling to maintain stable operating temperatures during high-power laser welding.

Water cooling provides effective thermal management for continuous industrial operation and helps maintain consistent laser performance during extended production cycles.

The system is designed for an operating temperature range of 0°C to 40°C.
