Beschreibung
Zusammenfassung:	The invention relates to a measuring device for performing measurements on a workpiece which are used to prepare and/or assess a weld seam produced by a welding device and having an initial portion and/or an end portion. The measuring device comprises a measuring unit comprising an optical coherence tomograph including a sample beam source, wherein the sample beam can be selectively focused on different measuring positions relative to a current machining position along the weld seam. The measuring device further comprises a fastening unit which is configured to attach at least the sample head to the welding device, and a control unit which is configured to dynamically adjust the leading beam and/or the trailing beam during machining along the weld seam. The invention further relates to a machining system, a method for performing measurements on a workpiece, and a method for machining a workpiece.
