Abstract
The present disclosure provides methods, devices, and systems for the butt welding of two, e.g., planar, workpieces composed of glass, e.g., quartz glass, by a pulsed laser beam, e.g., an ultrashort pulse ('USP') laser beam, which is directed into the workpiece material parallel to the joining surface of the two workpieces and which is focused into the workpiece material in the region of the joining surface to locally melt the two workpieces in the region of their joining surface, wherein the laser focus of the laser beam focused into the workpiece material is moved in or counter to the beam direction of the laser beam to produce in the region of the joining surface a weld seam extending along the beam direction.
