Laserline introduces the first blue 4 kW laser

Laserline will once again showcase its latest laser systems for joining and deposition welding at this year's Welding & Cutting show in Hall 5. This time the focus is on the world's first blue diode laser with an output power of 4 kW, which is said to have been developed for processing copper components. 

Its 445 nanometer wavelength is absorbed by copper and copper alloys, which is five times better than the typical infrared absorption of other lasers. This creates an unusually quiet molten pool, with no pores forming. It is said that the improved performance mainly ensures that laser welding is faster and more energy efficient, which of course improves the cost effectiveness of the process.

Laser welding and welding has come to the fore

Another highlight of Laserline in the field of connection technology is the "multi-point" optics for application-optimized beam shaping. The "multi-point" module was developed for use with Laserline diode lasers, enabling beam splitting to generate multiple individual points, with individual adjustments to the geometry and intensity distribution of the laser points. Thus, as Laserline explains, welding and welding processes can be implemented with highly personalized beam shaping, while the solder joints used have a high degree of positioning accuracy. Modules for stable and rapid brazing of hot galvanized sheets will also be demonstrated. There are also splash-free modules for symmetric or asymmetric welds with suitable penetration profiles.

Laser cladding protects the environment

As an option for segmental-deposition welding, Laserline in Essen is also showcasing a new 10 kW diode laser in the LDM series with a beam quality (100 mm mrad) suitable for many coating applications. The compact design of the 19" format (7 HU) enables the laser to be easily and quickly integrated into existing system concepts. As highlighted by Laserline, its package density is a previously unattainable 9.6 dm3/kW (one kilowatt of laser power requires less than 10 liters of installation space), so it requires only a third of the space occupied by an equivalent power fiber laser. In addition, Laserline has introduced a diode laser-based coating system for brake discs that can be used on plain bearing bolts for road and rail vehicles or planetary gears in wind turbines.
