Laserline at the Welding & Cutting 2025

New blue high-brilliance lasers for welding ultra-fine sheet metal structures and solutions for implementing more sustainable and efficient machining processes - these are the focal points of Laserline's presence at Schweißen & Schneiden 2025 (September 15 - 19, Messe Essen, Stand 5A11). The diode laser specialist will also be presenting a broad selection of its solution portfolio. The trade fair highlight is the new LDFblue 800-wbc diode laser system, which combines the proven LDF technology with the innovative blade engine from WBC Photonics for the first time. The laser offers an exceptional beam quality of 4 mm-mrad and is available with 400 or 800 watts of output power. Thanks to its high brilliance, the system is ideal for spatter-free welding of thin sheets with thicknesses of 100 to 200 µm, while at the same time offering high process stability, to which the robust, IoT-capable system architecture also contributes. An LDMblue 1800-30 with blue scanner optics and copper welding patterns will also be on display at the stand.

Laserline presents solutions for energy-efficient surface treatment

The trade fair portfolio also includes systems for industrial surface treatment such as heat treatment, paint curing, powder and polymer coatings and cladding. For example, the diode laser specialist will be presenting energy-efficient solutions for the environmentally friendly series coating of brake disks. The focus here is on the 30 kW diode laser, which enables significantly shorter process times thanks to its high performance class. Particularly noteworthy is the option of double-sided coating, in which both sides of the brake disc are processed simultaneously. This leads to more even heating of the workpiece and reduces the risk of deformation. Interested parties can also find out more about the new Active Process Fiber (APF) at the trade fair stand. The powerful hybrid solution for demanding industrial applications is particularly suitable for processes such as cutting, remote welding, coating and heat treatment, where a very small focus and high laser power are required. With its combination of a high-power diode laser source and two standard beam outputs, the system enables flexible application-specific switching between a standard process fiber and the APF - without the need for additional laser systems. The APF offers high brilliance at output powers of up to 6,000 W and is available with fiber core diameters of 50 μm and 75 μm. For applications with higher power requirements, a 1,000 μm standard fiber is available, which enables output powers of over 20 kW. The hybrid configuration offers users a flexible and efficient solution for a wide range of application scenarios - from fine material processing to large-area surface processes.
