摘要： A process for treating workpieces by means of laser radiation, particularlyor the cutting, hole burning and material removal with respect to metallic workpieces, in which the treated site of the workpiece is monitored by a radiation detector which contributes to reducing the intensity of the laser radiation when an upper limit value is reached and to increasing it when a lower limit value is reached. In order to achieve a controlled process without exceeding a critical temperature, such as the evaporation temperature, in a simple manner, the process is carried out such that, by the radiation detector, the heat radiation is measured which emanates from its treatment site, by which an upper temperature is monitored as the upper limit value of a predetermined temperature range and a lower temperature is monitored as the lower limit value of this temperature range, and in that the laser radiation, when the upper limit value is reached, is switched off and is switched on again when the lower limit value is reached.

摘要： The laser beam melts a plate or strip workpiece with the formation of a vapor capillary at a cutting point and the melt is driven off by a cutting gas consisting of a mixture of inert gas and hydrogen gas, the hydrogen gas making up to 25% by volume of the cutting gas. In order to maintain the vapor capillary, the cutting gas is taken to the surface of the melt at the cutting point at such a pressure and with such a pressure distribution that the temperature at the surface of the melt is kept at boiling point and the melt is continuously driven out of the cutting seam in the side away from the cutting direction of the vapor capillary. The plate or strip workpiece can be a magnetic steel sheet. An additional stream of gas, liquid, or solid particles can be used to move melt out of the cutting seam.

摘要： A process for material working with plasma induced by high-energy radiati especially laser radiation, in which the radiation originating from the region of the workpiece is observed along the axis of the laser radiation focused along the axis on the workpiece as a function of the time. To obtain a measure of the penetration depth of the vapor capillary in the workpiece the process is so carried out that exclusively the cross section of the vapor capillary is observed with a depth of field encompassing the entire workpiece thickness, and that the mean value of the intensity of the plasma radiation is used as a measure of the penetration depth.

摘要： A method of machining workpieces with a laser beam wherein the machining cess, in particular the melting depth or the through-melting distance is monitored by detecting an optical and/or acoustical signal created by an unshielded laser-induced plasma or vapor. In order to receive monitoring date which as much as possible is independent of signal variations in the process the signals are subjected to a frequency analysis and the average amplitudes (Ax, Ay) of two different frequency bands (x, y) of the analyzed frequencies are used with a predetermined calculation function to determine a rating value (B).

摘要： The invention relates to a device and method for structuring the surface of floor coverings which have already been laid, comprising various floor coverings which may also consist of mineral materials such as natural or artificial stone. The object of the invention is to provide floor coverings which have already been laid with a structure on their surface, which structure makes it possible to at least increase the nonslip properties even in the presence of slippy media, e.g. water. To do this, the invention uses a device with which at least one laser beam can be moved with controlled intensity and in at least one dimension across the surface to be structured, the elements for guiding and shaping the laser beam(s) being accommodated in a mobile part of the device, so that this mobile part is guided intermittently or continuously across the floor surface which is to be structured and, in the process, the structuring can be formed by means of the laser beam.

摘要： A waveguide is arranged in radial extension on a support mounted in rotary manner and whose pivot pin is parallel to the laser beam axis. The outer end thereof intersects the laser beam during a rotation of the support and in each case detects a partial beam of the laser radiation. By means of the waveguide, said partial beam is supplied to a detector, which is arranged in fixed manner in the pivot pin of the support. A hollow waveguide or light guide serves as the waveguide. A parallel displacement of the pivot pin of the support is possible by means of a stepping motor to enable the complete beam profile to be determined by a plurality of sections through the laser beam. In place of the stepping motor, the support can be provided with several waveguides of different lengths, distributed with the same angular spacing over the support circumference and which successively supply the detected partial beams to the same detector.

摘要： The invention relates to a method and a device for laser-beam welding, because the invention is especially suitable for deep welding a wide variety of materials. The object of the invention is to weld a wide variety of materials by means of laser radiation, especially by deep welding, with a reduced amount of work and at the same time good quality of the welded joint produced. The procedure adopted for this according to the invention is that the intensity of the laser radiation is set by beam-shaping in and on the surface of workpieces in such a way that a small area in the workpiece is irradiated with a great intensity, to form a steam capillary there, and a further, larger adjacent area on the workpiece surface is irradiated with a lesser intensity, and as a result a bell-shaped opening of the steam capillary is formed on the workpiece surface and the cooling rate of the melted material is reduced.

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.
