摘要： In order to harden the surface of workpieces having complex shapes withoutreviously applying absorption promoting surface layers, a mixture of inert gas and oxygen are supplied to the processing zone while the workpiece is exposed to laser radiation. The degree of absorption is maximized by adjusting at least one of the mixing ratio, the volume flow rate, and the processing temperature to conform to a nominal value.

摘要： A method is disclosed for manufacturing a molded body, in accordance with three-dimensional CAD data of a model of a molded body, by depositing layers of a metallic material in powder form. Several layers of powder are successively deposited one on top of the other, whereby each layer of powder is heated to a specific temperature by means of a focused laser beam applied to a given area corresponding to a selected cross-sectional area of the model of the molded body, before deposition of the next layer. The laser beam is guided over each layer of powder in accordance with the CAD cross-sectional data of the selected cross-sectional area of the model in such a way that each layer of powder is fixed to the layer below it. The method is characterized in that the metallic material in powder form is applied in the form of a metallic powder free of binders and fluxing agents, that it is heated by the laser beam to melting temperature, that the energy of the laser beam is chosen in such a way that the layer of metallic powder is fully molten throughout at the point of impact of said laser beam, that the laser beam is guided across the specified area of powder in several runs in such a way that each run of the laser beam partly overlaps the preceding run, and that a protective gas atmosphere is maintained above the interaction zone of the laser beam and the metallic powder.

摘要： A device for plating two or more metal plates, strips, etc., by the absoron of laser energy. The device is fitted with beam-forming optics which form the laser radiation into a beam with a rectangular cross-section. The radiation source is a laser-diode array in which several laser diodes are disposed next to each other in the same plane to give bars which can be laid next to each other, as well as stacked one on top of each other, in any numbers. In order to homogenize the laser radiation produced by the array to give a rectangular cross-section, the device proposed is fitted with special optics such as a prism which converges in the shape of a wedge, a glass plate, with a rectangular cross-section, reflective boundary drives, etc. The rectangular cross-section beam heats the two surfaces of the metal plates being plated only locally, over limited areas and to small depths, to the plastic state. In addition, sensors and control devices for control of the power of the laser-diode array and/or for changing the speed of advance of the metal plates being plated may be used.

摘要： A laser beam apparatus for the removal of surface layers from work pieces with a beam-emitting head that may be guided by hand and that is equipped with focusing optics, which is connected to laser apparatus that generates a laser beam so as to admit light, which exhibits a beam-deflecting direction that moves on a pre-determined pathway in an oscillating manner, which covers the laser beam radially with a point and releases it through an emission opening that faces the work piece, and which has a distance retainer that permits the adjustment of the distance of the beam-emitting head from the work piece. In order to achieve the possibility of its use under freehand guidance with great mean power outputs in the course of which acceptable area coverage rates, or rather processing times are to be rendered possible, the laser beam apparatus is embodied in such a way that the distance retainer is the point of the beam-emitting head that covers the laser beam radially, that the laser beam may be oscillated by the beam deflection apparatus on a pre-determined pathway by means of an exit opening of the distance retainer that has been adapted to the pathway, and that the focusing optics can alter the focusing of the laser beam depending upon the beam deflection in the sense of a focus that lies on the surface of the work piece.
