A device for joining by a laser beam two components along a ring-shaped contact zone, where a first of the two components is transmissive for the laser beam and a second of the two components is absorptive for the laser beam. The device includes a receptacle configured to affix the absorptive component and an internal clamping chuck configured for placement on the transmissive component within an open inside area of the contact zone. The device also includes 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, and a rotatable holding wheel. The pressure element is connected to the internal clamping chuck via an external axial bearing, the holding wheel and an internal axial bearing so as to transmit to the internal clamping chuck contact pressure exerted on the pressure element.
