A method for producing a receptacle which is closed by a sheet by transmission laser welding, and to an apparatus suitable to carry out same. The method and the apparatus are configured in such a way that a weld seam is formed between the wall structure of the receptacle and the sheet so as to be wider than the end faces of the wall structure.

Apparatus for laser transmission welding, method for laser transmission welding, and a receptacle which is produced thereby and is closed by sheet

Apparatus has a receptacle () for two workpiece parts () which extend two-dimensionally in X and Y directions and which are to be joined along a weld. The apparatus includes a laser beam source () comprising a plurality of individually controllable laser beam emitters () which collectively form a line array which is oriented in X direction, a transporting device () for transporting the laser beam source () relative to the receptacle () in Y direction, and a homogenizer () arranged downstream of the laser beam source () in the radiating direction. The homogenizer () has a carrier () in which is provided at least one reflection channel () with a channel cross section (QS) which is adapted to the course of the weld and a channel width (b) which is adapted to the width of the weld.
