6000W High Powered Fiber Delivered Direct Diode Lasers
High-powered fiber-delivered direct diode lasers have valuable applications in hardening and cladding processes. In hardening applications, these lasers serve as an excellent heat source for treating metal parts. They are used to prevent surface wear while preserving the metallurgical properties of the base material. A notable advantage of using laser hardening is the ability to achieve partial hardening, allowing for the preservation of a higher flexibility ferritic structure in other areas. This level of selective processing is typically not possible with techniques like induction hardening. Laser hardening also tends to result in minimal material warping, reducing the need for additional corrective measures to address workpiece deformations.
Laser cladding is another significant application of high-powered fiber-delivered direct diode lasers. This process involves fusing material onto a substrate, making it an additive manufacturing technique. Laser cladding is commonly employed in heavy construction industries to either create new surfaces for enhanced functionality or repair damaged surfaces that have worn down due to repeated use. During the laser cladding process, a laser beam generates a molten pool on the workpiece surface. Simultaneously, coating material, also melted by the laser, is added to this molten pool. The outcome is a metallurgically bonded layer that exhibits superior toughness compared to coatings produced through thermal spraying. Moreover, laser cladding is considered a safer and more environmentally friendly alternative to processes like hard chromium plating.
