Apparatus, systems, and/or methods are disclosed relating to welding systems that allow for virtual marking of welding workpieces. In some examples, a virtual marking process of the welding system generates and/or displays one or more markings on a display of the welding system in response to a dynamic input. In some examples, the dynamic input may comprise one or more of a user input received via a user interface, a marking instrument, and/or a welding gun of the welding system. In some examples, the dynamic input may comprise images captured by the welding system and recognized by the welding system as indicating markings. In some examples, the markings may guide an operator by indicating weld locations and/or weld order. In some examples, the markings may include embedded marking data (and/or metadata) that may be accessed and/or displayed to provide additional information and/or guidance to the operator.

In a method and device for assessing the quality of a processing operation, a workpiece with specific processing parameters is processed along a processing trajectory.
