A method for joining at least two parts by using ultrashort laser pulses of a laser beam of an ultrashort pulse laser is provided. At least one of the two parts to be joined is transparent for a wavelength of the ultrashort laser pulses. The method includes joining the at least two parts by using the ultrashort laser pulses of the laser beam along a joining seam. The joining seam has at least two joining points and a joining gap lying between the at least two joining points. Each joining point is longer than 10 μm.

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.

Methods and devices for monitoring a welding process for welding glass workpieces

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.
