Abstract:
1. A device for joining by a laser beam two components along a ring-shaped contact zone jointly formed by the components, a first of the two components being transmissive for the laser beam and a second of the two components being absorptive for the laser beam, the device comprising: a receptacle configured to affix the absorptive component; an internal clamping chuck having at least one contact surface configured for placement on the transmissive component within an open inside area of the contact zone; a pressure element with an open inside area that is larger than an extension of the contact zone; a laser source configured to emit the laser beam; a beam guide unit connected to the laser source and configured to direct the laser beam toward the contact zone; a beam guide control unit configured to control the beam guide unit; an external axial bearing; a rotatable holding wheel; and an internal axial hearing, wherein the pressure element is connected to the internal clamping chuck via the external axial bearing, the holding wheel and the internal axial bearing, so as to transmit to the internal clamping chuck contact pressure exerted on the pressure element, wherein the holding wheel includes a wheel hub, a wheel rim, and a plurality of wheel spokes connecting the wheel hub to the wheel rim.
