| 摘要 |
<p>The invention relates to a device, especially a laser hybrid welding head (1), for a laser hybrid welding process. Elements or structural components are arranged on at least one mounting plate (3). One element or one structural component can be formed by a laser (5) or an optical focussing unit, a welding torch (6) or a crossjet (7). The welding torch (6), especially a longitudinal centre line (14) that extends in the longitudinal direction of the welding torch (6), is arranged at an angle (15) of between 25 DEG and 45 DEG in relation to the laser (5) or the optical focussing unit, especially in relation to a laser axis (17) extending in the centre of the laser radiation (16). The laser axis (17) is provided with an angle of between 80 DEG and 100 DEG , preferably 90 DEG , in relation to the level of definition (10) or the surface (11) of the workpiece (12). The smallest gap between the laser beam (16) emitted by the laser (5) or the optical focussing unit and a welding wire (13), especially an end (22) of a welding wire, which exits the welding torch (6) amounts to between 0 and 4 mm.</p> |
