Laser Cladding With Pneumatic Powder Delivery

1 shows a general layout of the laser surface cladding with a pneumatic powder delivery.

Laser cladding with pneumatic powder delivery.

The exposure time is short which creates only a short delay as the cooling is quick. The flexibility and versatility of this process are noted together with the significant process improvement obtained using a reflective shroud and shot blasted specimen. The effect of the process parameters on the quality of the clad layer is discussed. Reconditioning of high value parts with local damages.

Anjos s 7 research works with 166 citations and 342 reads including. The filler material generally arrives in powder strip or wire form and gets introduced to the heat of the laser coaxially or laterally. The laser beam creates a molten pool at the workpiece surface to which is simultaneously added the laser coating material wire or powder molten by the laser. Lasercladding germany provides remanufacturing solutions to worn and damaged parts by laser powder cladding.

The powder injection nozzle is associated with the beam delivery system to direct the powdered hardfacing material to the interaction zone between the beam and the substrate the process sequences are shown in fig. A process of laser cladding using argon blown powder delivery is described. 3 a uniform and fine dendritic microstructure has been obtained as a result of the high cooling rates associated with laser cladding. 2 a pneumatic argon powder delivery system has been found to be an effective means of blowing a mixture of alloy and carbide particles into the laser generated melt pool.

Such method was applied in the present study. Laser clad valve seats were adopted on the production lines of toyota s japanese plants for mass production in 1997. 2 in the initial process stable cladding quality was achieved by fixing the process point of the laser powder and shielding gas and rotating the workpiece that is the cylinder head figure 4. Lct offers a wide range of optics for all coherent laser cladding core systems from fiber to the fiber coupled diode as well as options for both powder or wire delivery depending on the application requirements.
