Laser welding of thin sheets with positioner

Laser welding of thin sheets is one of the most advanced and precise methods to join materials with high weld quality and minimal interference to the surroundings. In this article, we focus on the specifics of laser welding with a positioner, specifically welding two 2 mm thick pipes using an IPG Lightweld 1500 welding machine without a wire feeder.

Advantages of using a positioner

The positioner in combination with laser welding allows precise control of the workpiece position during the welding process. This is particularly important when welding pipes, where an even and high-quality joint around the entire circumference of the pipe is required. The positioner, which can rotate the pipe around its axis, ensures even access of the laser beam to the surfaces to be welded, thus allowing a more perfect weld to be achieved around the entire circumference of the pipe.

Welding machine IPG Lightweld 1500

IPG Lightweld 1500 is a modern laser welder designed for precision welding of metal materials. This system is characterized by high flexibility, easy operation and exceptional stability of the welding process. Key features include:

Precise parameter settings: fine-tuning of the width of expansion, power and frequency ensures optimal results for different types of materials and applications.
High performance: thanks to the maximum power of 1500 W and the precise laser beam, quality welds can be achieved even with complex joints.
Weld protection: integrated pre-blow and post-blow shielding gas system minimizes oxidation and ensures aesthetic quality of the weld.
Ergonomic design: the compact design and intuitive touch controls allow easy handling and quick parameter adjustment, even for demanding operations.
Ramp-up and run-out: Gentle ramp-up and gradual weld termination features minimize heat stress and improve joint aesthetics.

These features make the IPG Lightweld 1500 the ideal choice for applications that require high precision and reliability, such as welding pipes or thin-walled materials with minimal thermal impact.

Welding of tubes without the need for further adjustments

Thanks to the advanced features of the IPG Lightweld 1500, pipes with a thickness of 2 mm can be welded all around without the need for further welding operations. This type of laser welding ensures that the joint is clean and of high quality without the need for additional grinding or cleaning of the weld after completion. This greatly reduces the time required to complete production and reduces the costs associated with additional operations.

Conclusion

Laser welding with a positioner is an efficient, fast and precise method for joining pipes and other metal parts. Using the IPG Lightweld 1500 welding machine and its advanced features such as power control, ramp, wobble frequency and gas functions, high quality welds can be achieved with minimal heat and without the need for additional maintenance. This process is ideal for applications that require high precision and reliability, and is suitable for a wide range of industries, from automotive to aerospace.
