JUYI QCW Pulse Fiber Laser Welding Machine

High-Precision Laser Welding with Stable Energy and Fast Processing

The JUYI QCW Pulse Fiber Laser Welding Machine is a precision welding system designed for small metal components and demanding industrial applications. Using QCW (Quasi-Continuous Wave) fiber laser technology, it combines high peak pulse power, stable energy output, precise heat control, and fast welding speed.

With laser power options from 100W to 450W and maximum pulse energy up to 90J, the machine can be configured for different welding materials, component sizes, and production requirements.

It is suitable for spot welding, seam welding, capacitor welding, relay welding, copper welding, stainless steel welding, and other precision metal joining applications.

Key Advantages

1. Stable Energy Output

Energy stability of less than ±1% helps maintain consistent laser output and repeatable welding quality during continuous production.

2. High Peak Pulse Power

QCW technology delivers concentrated laser energy in a short pulse, providing high instantaneous power for efficient welding of conductive and difficult-to-process metals such as copper.

3. Precise Heat Control

Pulse width from 0.05 to 50 ms and repetition frequency up to 5000 Hz allow welding parameters to be adjusted according to different materials and component requirements.

The concentrated heat input helps reduce the heat-affected zone and minimize thermal deformation.

4. Fast Welding and High Efficiency

The high energy density of the laser enables rapid melting and solidification, reducing welding cycle times and improving production efficiency.

5. Multiple Welding Modes

The system can support different welding requirements, including:

• Spot welding
• Seam welding
• Capacitor welding
• Relay welding
• Precision component welding

6. Low Operating Cost

Fiber laser technology requires fewer consumables and offers efficient operation with relatively low maintenance requirements, making it suitable for long-term industrial use.

QCW Fiber Laser Welding Technology

QCW, or Quasi-Continuous Wave, is a laser operating technology that combines high peak power with controlled pulse output.

The laser delivers energy in precisely controlled pulses rather than continuously. This allows the welding process to achieve high instantaneous power while maintaining accurate control over heat input.

The result is a concentrated welding process with fast energy transfer, controlled melting, and reduced thermal impact on surrounding areas.

This technology is particularly suitable for small components, thin metal parts, reflective materials, and precision welding applications.

Copper and Stainless Steel Welding

1. Copper Laser Welding

Copper has high thermal conductivity and reflectivity, making it more challenging to weld than many common metals. The high peak power of QCW laser technology provides concentrated energy for efficient copper joining.

Typical applications include:

• Copper terminals
• Electrical connectors
• Battery components
• Conductive parts
• Electronic components

2. Stainless Steel Laser Welding

The precise and localized heat input of QCW laser welding makes it suitable for stainless steel components requiring clean and repeatable welds.

Typical applications include:

• Stainless steel components
• Precision hardware
• Electronic housings
• Industrial parts
• Small metal assemblies
