Why Choose the WSX ND31A?

The WSX ND31A 4000W Galvanometer Welding Head offers a multitude of compelling reasons for selection in the field of welding applications.

High - Efficiency Performance

• Medium - Thick Plate Welding: Its compact structure is specifically engineered for medium - thick plate welding. This design allows it to operate with greater efficiency compared to many other welding heads on the market, enabling faster completion of welding tasks for thick materials.

• Multi - point Welding: In multi - point welding scenarios, the ND31A truly shines. With its high - speed and high - precision welding capabilities, it can rapidly and accurately complete multiple welds, significantly boosting production efficiency. This is especially crucial in mass - production environments where time is of the essence.

Long - Term Stability

• Water - Cooled Design: The collimator, galvanometer, and field - flattening lens all feature water - cooled structures. This advanced cooling system helps maintain optimal operating temperatures, preventing overheating and ensuring long - term, stable performance. As a result, the welding head can operate continuously for extended periods without a significant drop in performance.

• Sealed Structure: The internal structure of the welding head is fully sealed. This not only protects the delicate optical components from dust and debris but also enhances the overall durability of the device. By keeping out contaminants, the lifespan of the welding head is extended, reducing the need for frequent maintenance and replacements.

Versatile Welding Modes

• Multiple Swing Patterns: The motor - driven X and Y axis galvanometer mirrors, combined with the F - THETA focusing lens group, enable the ND31A to achieve multiple swing modes. This versatility allows for greater flexibility in welding different types of workpieces, whether they have complex shapes or require specific welding techniques. It can adapt to a wide range of welding requirements, making it a valuable asset in various industrial settings.

Lens Protection

• Air Curtain Component: The inclusion of an air curtain component is a significant advantage. It acts as a protective barrier, reducing the amount of welding fumes and splash residues that reach the lenses. This helps maintain the clarity of the lenses, ensuring consistent welding quality and reducing the frequency of lens cleaning or replacement.

Compatibility

• QBH Connector: The ND31A is equipped with a QBH connector, which allows it to be easily connected to various lasers. This compatibility means that users can integrate the welding head into their existing laser systems without the need for extensive modifications, providing a cost - effective and convenient solution.

Technical Specifications

Power and Focal Lengths

• Applicable Power: The WSX ND31A is designed to handle a power of 4000W, making it suitable for a wide range of medium - to high - power welding applications.

• Collimation Focal Length: It offers two options for collimation focal length: 100mm and 150mm. These different focal lengths provide flexibility in adjusting the laser beam before it enters the welding process, allowing for optimal beam shaping according to the specific requirements of the workpiece.

• Focusing Focal Length: There are three choices for focusing focal length: 254mm, 350mm, and 400mm. This variety enables users to select the most appropriate focal length for different welding distances and workpiece geometries, ensuring precise and efficient welding.

Scanning Range

The scanning range of the ND31A varies depending on the focusing focal length used:

• For a focusing focal length of F161, the scanning range is 55 * 55 mm.

• When using a F254 focusing focal length, the scanning range expands to 110 * 110 mm.

• With a F350 focusing focal length, the scanning range reaches 200 * 200 mm.

• For a F400 focusing focal length, the scanning range is 220 * 220 mm. This wide range of scanning capabilities allows for welding of different - sized workpieces, from small - scale components to larger structures.

Physical Characteristics

• Weight: The welding head weighs 8kg, which is a manageable weight for most industrial setups. Its relatively light weight makes it easier to install, position, and manipulate during the welding process.

• Effective Clear Aperture: The effective clear aperture is 24mm. This aperture size allows for a sufficient amount of laser energy to pass through, ensuring high - quality welding performance.

Connectivity

• QBH Connector: As mentioned earlier, the ND31A is equipped with a QBH connector. This connector is a standard in the laser industry, providing a reliable and efficient connection to various lasers. It ensures seamless integration with different laser sources, enhancing the versatility and usability of the welding head.

• Compatibility with Various Lasers: The welding head is designed to be compatible with a wide range of lasers. This compatibility gives users the freedom to choose the laser that best suits their specific welding needs, whether it’s a fiber laser, CO₂ laser, or other types of lasers commonly used in industrial welding applications.
