Abstract
A connection arrangement comprising a metallic flat conductor having an at least quadrangular cross-sectional profile and at least two mutually opposing first and second surfaces extending at least partially parallel to one another in the longitudinal direction, at least two parts which are flat in the overlap region and which are formed as connecting lugs and which rest on the first surface with an overlap joint and project beyond one or both longitudinal edges of the flat conductor, characterized in that a metallic friction stir welded joint zone is formed starting from the second surface through the flat conductor towards the first surface and projecting into the connecting lugs.
