The invention concerns a laser device for joining work pieces made of plastic by means of beam welding technology, with a processing head that has focusing devices for the laser beam. Here, the focusing device that is closest to the work pieces has a rotatably supported cylinder lens in the shape of a roller that focuses the laser beam along a single axis and presses the work pieces together in the form of a line in an area around the impact point of the laser beam. In order to enable the cylinder lens to always contact the surface of the work piece facing the processing head in a precisely tangential manner, the processing head has a pendulum-type suspension for the rotatable cylinder lens. This also makes it possible for the contact pressure exerted by the processing head to always act perpendicularly on the work pieces so that they are pressed together in all welding places in the same way in a defined manner during the welding process.
