Abstract (en)

[origin: WO2018146303A1] The invention relates to a method for identifying joining points of workpieces and to a laser machining head comprising: a housing, through which a work laser beam path (10) is passed, and a device for carrying out the method for identifying joining points of workpieces, which device has: a camera (16) for capturing images of a joining point (6) of workpieces, the viewing beam path (17) of the camera being coupled coaxially into the work laser beam path (10); and an illumination device (19), the illumination beam path (21) of which is coupled coaxially into the viewing beam path (17) and into the work laser beam path (10). In said method, images of a joining point are captured by a camera (16) and from the images of the joining point (6) measurement data for the joining points is determined, which measurement data is associated with the course of the joining point (6). A model of the course of the joining point is determined from one portion of the measurement data, the model providing a data curve that was adapted to the measurement data with the aid of the model, said curve being output in order to control a joining process and/or to determine additional quality characteristics.
