About Laserline
Laserline GmbH, headquartered in Mülheim-Kärlich, develops and manufactures high-power diode lasers for industrial material processing in the multi-kW range. With over 25 years of experience in this field and more than 8,500 systems in operation worldwide, the modular, efficient and low-maintenance beam sources are among the established solutions for laser welding, brazing, hardening, coating (laser cladding/laser metal deposition) and additive manufacturing. A particular focus lies on blue diode lasers for processing copper, gold and their alloys, for example in copper welding and powder-bed metal printing. In addition to system manufacturing, the company offers application development, application trials, training, commissioning and service through to series production support. Customers come primarily from automotive and e-mobility, oil and gas, aerospace, tool and die making, renewable energy, semiconductor and battery production, as well as heavy industry.
