This Is How Beam Shaping Affects Laser Welding

One of the most advanced beam shaping technologies has been developed by Civan Lasers with its "Dynamic Beam" laser. This method allows beam shapes to be designed via software, enabling the creation of any desired beam shape at very high power. This capability has demonstrated that many new applications, previously inaccessible to laser welding, can now be successfully implemented. The "Dynamic Beam" laser technology offers significant advantages in the world of joining, as it allows precise control over the shape and distribution of the laser beam. This variability leads to better process management of the molten material during welding, reducing defects and improving weld quality. The technology also enables the welding of different materials and material thicknesses that are difficult or even impossible to weld using conventional methods.

Laser Welding Makes Previously Impossible Connections Possible

The joining of thick sheets made of structural steels or chromium-nickel steels with thicknesses over 20 millimeters, traditionally carried out using arc welding processes, requires approximately ten layers for double-sided welding. In this process, the part must also be rotated multiple times, which can take several hours for a single weld, including cooling times. In contrast, the "Dynamic Beam" laser can complete this process in just two minutes with one to two weld layers. Beyond the ability to weld faster and replace conventional welding methods, this laser technology also opens up new possibilities for welding materials previously considered unweldable—such as aluminum die castings or even additively manufactured or 3D-printed metal parts. This capability presents an opportunity to rethink the use of such components, as multiple small individual parts can be joined into large components, simplifying and reducing the cost of manufacturing. In recent years—and even in recent months—there have been increasing publications highlighting the laser's potential for applications previously deemed impossible. This trend points to the start of a new era in welding technology. Since laser welding now enables the joining of thick profiles and materials previously deemed unweldable, it has become an attractive technology due to its advantages (high feed rate, clean weld seams, low power consumption, and minimal fume development) and is worth consideration for use.

This Can Already Be Said About the Future of Laser Welding:

Laser welding is also excellently suited for automation. And as automation continues to advance across all sectors, the integration of laser welding into manufacturing processes will keep expanding. The future will bring new applications for laser welding, enabled in part by the development of laser beam shaping. It is also evident that increasingly powerful laser technology aligns well with other trends in clean manufacturing and automation. This connection strongly indicates that laser welding, combined with dynamic beam shaping, will become an indispensable part of modern joining technology. (pk)
