Laserline at EuroBLECH 2024

At EuroBLECH 2024, October 22 through 25, 2024, Hanover, Germany, Laserline will be presenting solutions for processing sheet metal, copper and aluminium components. Key topics include blue 4 kW CW diode lasers for copper welding, solutions for laser curing of powder coatings and multi-spot optics for application-optimized beam shaping.

The latter enable beam splitting to create several individual spots as well as the spot-specific adjustment of geometry and intensity distribution. They are used for the smooth and fast brazing of hot-galvanized steel sheets or for the realization of symmetrical or asymmetrical seams with less spatters and an adaptable penetration profile. In addition, optics for aluminium welding with hot wire (Hot Wire Aluminum Welding) will be showcased. The process offers more process stability than conventional aluminium joining processes and scores points for its reduced heat input into the base material and high process speed with a high seam quality.

In addition to the processing optics, Laserline will also be exhibiting various beam sources: One focus will be on fiber-coupled mobile diode lasers from the LDF series, which offer output powers of more than 45 kW in various system configurations. The LDF lasers are characterized by their flexible scalability and can be upgraded in the field from 12 to 24 kW, for example. For the increasingly important industrial processing of non-ferrous metal components, Laserline is also presenting its portfolio of solutions in the field of blue high-power diode lasers – with output powers of up to 4 kW. Their wavelength of 445 nm is absorbed by copper and copper alloys better than infrared wavelengths, which ensures smooth melt pools without pore formation.

Another focus of the tradeshow presentation is the laser curing of powder coatings using "Ultra Wide Spot" technology, which presents an economic and ecological alternative to gas-fired oven processes. The laser heats only the exact area that needs to be coated, without causing any particle dispersion. Since the laser systems do not require any heat-up time and the laser power can be adjusted within milliseconds while the process is running, it is possible to achieve a 90 per cent increase in heating rate and higher overall energy efficiency.

In addition energy- and material-efficient cladding solutions, including brake disc cladding for road vehicles will be showcased. Laser cladding ensures long-term protection against corrosion and wear and reduces the amount of fine dust caused by the braking process – dust that is harmful to both the environment and human health – by up to 90 per cent. This makes a crucial contribution to more sustainable mobility.

The trade fair presentation will be rounded off with selected exhibits from individual application areas, including an underride guard for a car and samples for welding tailored blanks.
