    • The invention relates to a method for operating a device for material processing workpieces by means of lasers (10), in particular a laser welding device, according to which method at least one optical feature characterizing the process is detected by at least one detection means (17) and at least one control parameter (P) for controlling the process energy formula (II) is generated by at least one data processing unit (19) using the control signal formula (I) derived from the optical feature. In order to provide a method for material processing by means of lasers, in which a process control is carried out in a simple manner for preventing negative effects on the processed workpiece (i), said control being stable despite a limited range of values of the control signal formula (I), in the sense that said control return to the process energy formula (II) at any time wherein the feature characterizing the process changes state, and, as long as the process remains near the required process energy formula (II), the control has high quality, according to the invention an optical feature having a transition between at least two states for at least one particular value of the process energy formula (II) is used for the method, and the process energy formula (II) is controlled at a controlled amplitude by considering the history (H) of the control signal formula (I) and/or the control parameter (P) for the method.
    • 本发明涉及一种用于通过激光(10)的装置操作的装置的工件材料加工,尤其是激光焊接装置,在该方法中使用至少一个检测装置(17)在加工过程中表征的光学特性中的至少一个被检测,并且由至少一个数据处理单元(19) 所导出的特征的从用于控制所述过程的能量式(II)的光控制信号的式(I)的至少一个操纵变量(P)的基础上被生成。 为了具有用于通过可用的,其中通过防止在过程控制以简单的方式,这是在一种意义上稳定进行的加工的工件(ⅰ)负面影响激光的手段,在处理材料尽管控制信号式(I)的值的有限范围内的方法,即 随时返回到过程中的能量式(II),其中,所述过程的特性特征改变其状态,并且只要该过程中所需要的过程中的能量的附近是式(II)具有高控制性能,建议,在这种 的方法使用光学功能,至少式(II)的过程中的能量的至少两个状态之间并且在该方法的过程中的能量式(II)通过考虑控制信号的式(I)的历史(H)和过渡的特定值 /或操纵变量(P)具有受控振幅控制为reg 踏板。
