Abstract
A method for making a tubular element, in particular a motor vehicle front cross member (1), for forming at least an air conduit (2,3,4) including at least two half-shells (5,6) assembled on two outer longitudinal edges (5a, 6a-5b, 6b), facing each other, with punctiform mechanical bond elements (7). The method further comprises the production of sealing elements (8) for the tubular element (1) consisting of at least a continuous convex or concave deformation simultaneously produced on each of the outer longitudinal edges (5a, 6a-5b, 6b) facing the two half-shells (5 and 6), in the proximity of the mechanical bond elements (7).
