The elliptical spot welding head is a vital innovation in laser welding technology, designed to improve the precision, strength, and efficiency of welds in a variety of applications. This component leverages two cylindrical mirrors aligned orthogonally on the X and Y axes to reshape the laser beam from a circular spot to an elliptical one, achieving an ideal welding point. Thanks to its compact size and lightweight design, the elliptical spot welding head minimizes the risk of overheating or damaging surrounding materials, supports single-pass welding, and provides a larger weld area for enhanced bonding strength.

Advantages of Han’s Laser Elliptical Spot Welding Head

1.Customizable Design

Equipped with an LLK-B fiber connector, the elliptical spot welding head is exceptionally compact and lightweight, making it highly adaptable to small robotic systems and narrow spaces. This design also offers multi-function compatibility, allowing for customized spot shapes and sizes to match the specific dimensions and requirements of each product, ensuring flexibility across diverse applications.

2.Adjustable Collimation

The welding head features an adjustable collimation range of ±3mm, allowing for precise control over the beam’s focus. This adjustability enhances the accuracy of the weld, ensuring that each application meets the highest standards.

Single point welding

Continuous welding

3.Fine-Tuned Cylindrical Mirror Adjustment

The cylindrical mirrors can be adjusted with a ±1mm range. This alignment is achieved by fine-tuning the set screws on either side of the mirror, which helps maintain the coaxial alignment of both mirrors. This feature is critical for achieving consistent beam quality and precise elliptical spot shaping.

Application Areas

The elliptical spot welding head is particularly well-suited for use with compact robotic arms and in confined spaces, making it ideal for in-mold welding applications. It is widely used in the connector and plug industries, where precise, strong, and reliable welds are essential. By expanding the weld area while ensuring a secure and clean bond, this component supports efficient production and meets the rigorous demands of these high-precision fields.

Conclusion

The elliptical spot welding head from Han’s Laser customizable design, compact size, and adjustable features make it an invaluable tool for industries that require high-quality welds in tight spaces, such as the connector and plug sectors. By enhancing weld accuracy and durability, this innovative component supports efficient, reliable manufacturing processes, empowering businesses to meet the demands of modern production with confidence.
