Abstract
The present disclosure relates to methods and systems for monitoring a welding process for welding at least one glass workpiece to another workpiece, e.g., also made of glass, wherein a weld seam is formed in the workpieces in a process zone that is exposed to a pulsed processing beam, e.g., to a pulsed laser beam, such as an ultra-short-pulse laser beam, wherein the radiation emitted by the process zone is detected in a time-resolved manner.
Claims21
A method for monitoring a welding process for welding at least one glass workpiece to a further workpiece, the method comprising
- forming a weld seam in the workpieces in a process zone that is exposed to a pulsed processing beam;
- and
- detecting radiation emitted by the process zone in a time-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 pulsed processing beam;
- and
- a sensor arranged and configured for time-resolved detection of radiation emitted by the process zone.
