In a method of making a cross member for a twist-beam axle of a motor vehicle, a band-shaped metal blank is shaped in a profiling unit in a continuous operation to a V-shaped or U-shaped double-walled hollow section having an outer wall and an inner wall, such that the outer wall of the hollow section extends, at least in an apex area thereof, at a distance to the inner wall of the hollow section, and that confronting longitudinal edges of the hollow section extend in the apex area of the outer wall. The confronting longitudinal edges of the hollow section are then joined by a longitudinal weld seam which is then smoothed. Subsequently the welded hollow section is cut to size to form a cross member.
