| 摘要 |
The invention concerns a process for pretreatment of a workpiece to be processed with a laser beam, as well as a device for carrying out the process. It is the task of the invention to develop a process and a device, which with small expenditure of material and expense, and with few process steps, makes possible an improved weld seam formation for joining workpieces. The invention is comprised therein, that for the pretreatment of a workpiece to be treated with a laser beam, in which on at least one surface of the workpiece with application of a thermal effect of at least one laser beam emitted by a laser source, rises such as knurls are formed, for the positionally correct and undistorted formation of the rises the time and spatial sequence of a relative movement between workpiece and laser beam and the output over time of the laser source are coordinated to each other via a control computer.
