Abstract
A welding device has a beam source to generate electromagnetic beams for absorption in an object to be welded at a welding location, and at least one sensor situated to detect electromagnetic process beams generated during welding at the welding location. The sensor is to generate a sensor signal as a function of the detected process beams. The welding device also has a processing unit, which is connected to the sensor and the beam source, the processing unit being configured to control at least one parameter of the beam generation of the beam source as a function of the sensor signal. The welding device is to delimit by a window a beam bundle of the emitted process beams in a plane transverse to the beam propagation direction; in the plane, the window has a longitudinal dimension greater than a transversal dimension of the window perpendicular to the longitudinal dimension.
