摘要： A rolling mill is rotated while microscopic dents with peripheral ridges are formed by an intermittent laser beam in the presence of a gas jet directed at the beam impact zone. The output and the angle of incidence of the gas jet are controlled and microscopic dents are formed with a ridge on only part of their periphery. Steel sheet cold-rolled by means of such a roll has uniformly distributed hollows, each hollow partially surrounding an elevation.

摘要： A method for treating the surface of a roll, e.g. for a rolling mill, by focusing a substantially continuous concentrated corpuscular beam, e.g. a laser beam or an electron beam, on the roll surface, guiding the beam to impinge on the roll surface in a helical path, and regulating the concentration of the beam, the relative speed of rotation of the roll, and the translation speed of the beam so that the ratio of the pitch of the helical path and the width of the path of the beam on the roll surface is less than 1.

摘要： Apparatus and method are disclosed for machining and, in particular, welding a work piece in an environment comprised of a gas non-reactive to the material of the work piece to minimize the contamination of the welds effected on the work piece. In an illustrative embodiment of this invention, there is provided a welding chamber for receiving the work piece and for establishing the welding environment therein. The welding chamber has an input port disposed in a bottom portion thereof, that is coupled to means in the form of a controllable pump for directing or pumping the non-reactive or inert gas, e.g. argon, through the input port and into the welding chamber. The welding chamber also includes an output port, whereby the non-reactive gas may escape from the welding chamber. A diffuser plate distributes the non-reactive gas substantially uniformly across the cross section of the welding chamber, whereby a laminar flow of the non-reactive gas is directed over the work piece and is permitted to escape through the output port.

摘要： A development of a laser cutting method and a laser cutter in which the adverse effects such as self burning to the cutting surface can be prevented, when the material is cut at a high speed, has been desired. In order to achieve the object, the present invention provides a laser cutting method and a laser cutter in which a cutting laser beam 22 is applied to a material 25 to be cut at a cutting point 26, while ejecting gases 23 and 24 to the cutting point 26 or its surrounding area from a plurality of nozzle openings 30 and 31 arranged in a ring or in a line, wherein the oxygen concentrations of the gases 23 and 24 ejecting from at least one of the nozzle opening 30 and 31 are changed to adjust the oxygen concentration distribution in an area within several millimeters of the cutting point 26; thereby the cutting quality can be improved.

摘要： The present disclosure generally relates to additive manufacturing systems and methods on a large-scale format. One aspect involves a build unit that can be moved around in three dimensions by a positioning system, building separate portions of a large object. The build unit has an energy directing device that directs, e.g., laser or e-beam irradiation onto a powder layer. In the case of laser irradiation, the build volume may have a gasflow device that provides laminar gas flow to a laminar flow zone above the layer of powder. This allows for efficient removal of the smoke, condensates, and other impurities produced by irradiating the powder (the “gas plume”) without excessively disturbing the powder layer. The build unit may also have a recoater that allows it to selectively deposit particular quantities of powder in specific locations over a work surface to build large, high quality, high precision objects.

摘要： Provided is a laser welding apparatus that performs welding by irradiating a laser beam onto a welded part, the laser welding apparatus including: a shielding gas supply unit that supplies a shielding gas to the welded part; a gas feed rate controlling unit that controls a flow rate of the shielding gas; a light intensity measurement unit that measures a light intensity of plasma light emitted from the welded part; and a rate-of-change calculation unit that calculates a rate of change of the light intensity measured by the light intensity measurement unit. The gas feed rate controlling unit controls, according to the calculated rate of change of the light intensity, the flow rate of the shielding gas supplied to the welded part.

摘要： The head (9) of the cutting apparatus (4) of the laser comprises a gas supply through a device such as a barrel dispenser which chops the blowing flow rate, which produces a better discharge of the liquid slag melt by the laser beam (16, 18) out of the plate (19) to be cut. A measurement (36) of backscattered light is made in order to check the good quality of cutting, the amount measured being smaller if the cutting actually passes through the plate (19), and the frequency or the pressure of the blowing pulses is adjusted by a controlling device (39) to keep the measure to a minimum by optimizing the slag discharge conditions.
