Zusammenfassung:	The present invention relates to a welding method (100) for laser welding a flexible film to a substrate (219, 403). The film comprises a conductor layer (213, 401) which is surrounded by plastic layers. The welding method (100) comprises: a cutting step (101) in which incisions are made in at least portions of the conductor layer (213, 401); a deforming step (103) in which the cut conductor layer (213, 401) is moved onto the substrate (219, 403) portion by portion; and a welding step (105) in which the cut conductor layer (213, 401) and the substrate (219, 403) are welded together by means of a laser (201).
