1. A method for joining workpieces by means of a processing beam, comprising the joining of a first of the workpieces to be joined with a second of the workpieces to be joined at a joint by means of the processing beam producing a weld seam, the capturing of one or more thermal images of a joint portion heated by the processing beam, wherein each of the thermal images comprises a first thermal imaging section, which characterizes the temperature distribution of the first workpiece, and a second thermal imaging section, which characterizes the temperature distribution of the second workpiece, and the evaluation of the thermal images with respect to joining flaws, characterized in that an evaluation of the thermal images is performed with respect to the positioning of the processing beam (7) and the positioning of the processing beam (7) is performed based on the result of the evaluation of the thermal images. |
