Diode Lasers in Use

Powerful | Compact | Individual

The flexibility of our high-power diode lasers offers a wide range of applications for users in production processes worldwide. Diode lasers have become indispensable in many industrial sectors. Typical areas of application for Laserline diode lasers are classic industrial metalworking processes such as welding, brazing, hardening, softening and the creation or repair of coatings. Laserline diode lasers have also established themselves in plastic welding and in newer manufacturing processes such as additive manufacturing (metal 3D printing) or the welding of fiber composites.
