JUYI Pulsed Nd Laser Welding Machine

Stable, Precise and Efficient Laser Welding for Metal Components

The JUYI Pulsed Nd Laser Welding Machine is a precision laser welding system designed for high-quality metal joining, component repair, and industrial manufacturing applications.

Powered by an Nd laser source with a 1064 nm wavelength, the machine provides stable laser output, adjustable pulse parameters, and precise heat input. With a main laser output power of 500W and maximum single pulse energy of 100J, it is suitable for welding a wide range of metal components with different sizes and thicknesses.

The machine supports adjustable pulse repetition frequency and pulse width, allowing users to optimize welding parameters for different materials and applications. With a maximum welding penetration of up to 2 mm and continuous operation for up to 24 hours, it provides a reliable solution for both precision welding and continuous industrial production.

Key Advantages

Stable Laser Performance

The Nd laser source provides stable and consistent laser output for reliable welding quality. Laser power instability is controlled within ≤ ±3%, helping maintain consistent processing results during production.

Adjustable Pulse Parameters

The pulse repetition frequency can be continuously adjusted from 0–200 Hz, while pulse width can be adjusted from 0.2–50 ms.

This flexible parameter control allows the welding process to be optimized according to:

• Material type
• Material thickness
• Joint configuration
• Required penetration
• Welding speed
• Heat input

High Single-Pulse Energy

With maximum single pulse energy of 100J, the machine can deliver concentrated energy to the welding area, supporting deeper and more efficient welding of metal components.

Maximum welding penetration can reach up to 2 mm, depending on the material and welding conditions.

High Welding Efficiency

The concentrated laser beam enables rapid local heating and melting, reducing unnecessary heat transfer to surrounding areas.

This helps improve:

• Welding speed
• Production efficiency
• Weld consistency
• Heat control
• Processing accuracy

Long Continuous Operation

The system is designed for continuous operation of up to 24 hours, making it suitable for industrial production environments requiring stable and reliable equipment performance.

Precise Beam Control

With beam divergence of ≤10 mrad, the laser provides controlled energy delivery for accurate welding and localized heat input.

This is particularly useful for small components, precision parts, and applications requiring controlled welding areas.

Pulsed Nd Laser Welding Technology

Pulsed Nd laser welding uses short-duration, high-energy laser pulses to generate localized heat at the welding point.

The process can be controlled by adjusting pulse energy, pulse width, and repetition frequency according to the material and welding requirements.

The basic process is:

Laser Pulse Generation → Concentrated Energy Delivery → Localized Melting → Weld Formation → Rapid Solidification

Compared with conventional welding methods, pulsed laser welding provides more precise control of the welding area and heat input, making it suitable for precision metal joining and repair applications.
