3000W Fiber Delivered Direct Diode Lasers
High-powered fiber-delivered direct diode lasers are primarily utilized in hardening and cladding applications. In hardening, lasers serve as an excellent heat source for treating metal parts to prevent surface wear while preserving the base material's metallurgical properties. This process allows for selective partial hardening while maintaining the desired flexibility of the ferritic structure in other areas. This level of selective processing isn't achievable with induction hardening. Laser hardening also typically results in minimal warping of the material, often eliminating the need for additional corrective measures to address workpiece deformations.
Laser cladding is an additive manufacturing process in which material is fused onto a substrate. It finds extensive use in heavy construction industries for creating new surfaces to enhance functionality and repairing damaged surfaces worn down by repeated use. In the laser cladding process, the laser beam generates a molten pool on the workpiece surface, and coating material, also melted by the laser, is simultaneously added to this pool. This results in a metallurgically bonded layer that is tougher than coatings produced through thermal spraying. Moreover, laser cladding is a safer alternative to processes like hard chromium plating in terms of health and environmental concerns.
