Abstract
The present disclosure relates to methods and devices for monitoring a welding process for welding at least one glass workpiece to another workpiece, the workpieces being welded together in a process zone that is exposed to a processing beam, e.g., to a laser beam, such as an ultra-short-pulse laser beam, wherein radiation emitted by the process zone and originating from at least one of the workpieces is detected in a spatially resolved manner.
Claims21
A method for monitoring a welding process for welding at least one glass workpiece to a further workpiece, the method comprising
- welding the workpieces together in a process zone that is exposed to a processing beam;
- and
- detecting radiation emitted by the process zone and originating from at least one of the workpieces in a spatially resolved manner.
A device for monitoring a welding process for welding at least one glass workpiece to a further workpiece, the device comprising
- a processing objective for exposing a process zone of at least one of the workpieces to a processing beam;
- and
- an image sensor arranged to detect radiation emitted by the process zone and originating from at least one of the workpieces in a spatially resolved manner.
