1. A method for assembling a first metal part with a second part made of an organic matrix composite material, the first part having a first connecting portion and the second part having a second connecting portion, the method comprising:
overlapping the first connecting portion and the second connecting portion, such that a through-hole of the second connecting portion opens onto the first connecting portion, wherein the through-hole has a side wall,
forming a protective layer at least on the side wall of the through-hole,
forming a seal between the protective layer and the first connecting portion, and
forming, by additive manufacturing using cold gas spray deposition of metal powder, a fastening element which extends into the through-hole, fastened to the first connecting portion and enclosing the second connecting portion.
