Independent claims are also included for: (1) a device (200) for a laser joining using a laser-remote method, preferably for a scanner joining, e.g. for a scanner welding and/or a scanner soldering, comprising at least one beam distraction optical system (20), preferably at least one flexible optical scanner and/or at least one tiltable mirror system by which at least one laser beam (12, 14) is led over at least one area to be joined, preferably at least one area to be welded and/or to be soldered, and at least one unit; (2) supplying the protective gas and/or at least one protective gas mixture to at least one area to be joined, preferably to be welded and/or to be soldered, using the unit, comprising supplying the protective gas and/or the protective gas mixture, controlling and/or regulating the supply of the inert gas and/or inert gas mixture, preferably controlling and/or regulating the nature, pressure and/or volume of the protective gas and/or inert gas mixture, and associating the supply of the protective gas and/or the inert gas mixture to the area to be joined; and (3) the use of at least one protective gas and/or at least one protective gas mixture during laser joining by means of a laser-remote method, preferably in scanner joining, e.g. the scanner welding and/or the scanner soldering, using at least one unit, at least one device and/or the method mentioned above. #CMT#USE : #/CMT# The unit is useful for supplying at least one inert gas and/or at least a protective gas mixture to at least one area to be joined, preferably to be welded and/or to be soldered. #CMT#ADVANTAGE : #/CMT# The unit: exhibits a compact design; comprises the gas supply, the control unit and the fastening element, which are together, easily and quickly installed; is used in variety of devices for joining, preferably for laser joining, thus it is flexible, interchangeable and reusable; and provides improved and adjustable supply of protective gas and joint seam improved with geometry and/or the appearance. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure 1 shows a schematic representation of the device comprising many units for supplying protective gas and/or protective gas mixtures. 12, 14 : Laser beam 20 : Beam distraction optical system 50 : Fastening element 100 : Unit 200 : Device #CMT#INSTRUMENTATION AND TESTING : #/CMT# Preferred Components: The unit: comprises at least one storage device, preferably at least one cylinder with process gas and/or process gas mixture to provide the protective gas and/or the protective gas mixture; at least one magnetic valve associated with the gas supply unit, where the magnetic valve regulates the supply of protective gas and/or inert gas mixture, preferably depending on the joining process, e.g. synchronized with at least one welding sequence and/or at least one soldering sequence; and at least one continuous valve, preferably continuous solenoid valve associated with the gas supply unit, where the valve controls and/or regulates the gas pressure and/or the gas flow rate of the supplied protective gas and/or the supplied protective gas mixture. The unit is magnetically attached preferably to the gas supply unit using the fastening element, which is detachably mounted on the area to be joined or on the area to be joined, which is associated with the holding device, and/or using at least one screw compound. The respective gas supply units are independent, where preferably at least two units exhibit different gas supply units, e.g. at least one of the unit exhibits a process gas nozzle with a magnetic valve and at least one other unit exhibits a process gas nozzle with a proportional solenoid valve. At least two of the units exhibit at least its own supply with protective gas and/or protective gas mixture, preferably at least its own gas storage device, e.g. its own at least one cylinder with process gas or process gas mixture, for providing the inert gas and/or the protective gas mixture. The control-/regulating-unit of at least two units is individually controlled and/or selectively addressed, preferably controlled or regulated simultaneously or sequentially in time using at least one superior control-/regulating-unit. The fastening element of the gas supply unit is associated with a working area or a working space reachable by at least one laser beam, where at least two units are associated with the same working area or working space. #CMT#ORGANIC CHEMISTRY : #/CMT# Preferred Method: The supply of the protective gas and/or inert gas mixture is carried out in at least two different laser joining operations, preferably in at least two different scanner joining operations, e.g. at least two different scanner welding operations and/or at least two different scanner soldering operation in the same working area or working space of the laser beam. At least two different protective gas, at least two different protective gas mixtures or at least one protective gas and at least one protective gas mixture is supplied, and different materials, preferably different valuable materials, and/or different coated materials, preferably different valuable materials are joined.</p> |
