1. A method for producing a fluid connection arrangement, comprising:
providing a receiving part comprising a receiving wall that has a receiving wall inner side that delimits an interior of the receiving part;
providing a tubular connecting part that comprises a tube wall having a plurality of comb-shaped support points that extends along a longitudinal direction of the tubular connecting part and having at least one curved wall area that extends between two adjacent comb-shaped support points of the plurality of comb-shaped support points, wherein providing the tubular connecting part comprises press forming a tubular precursor with a concentric cross-section to obtain the tube wall of the tubular connecting part with a rotationally symmetrical cross-section comprising the plurality of comb-shaped support points and the at least one curved wall area, wherein the press forming comprises a circumferential action of a plurality of jaws of a forming tool on the tubular precursor, wherein the press forming of the tubular precursor ensures a uniform forming and a constant wall in the tubular precursor;
at least partially inserting the tubular connecting part into the interior of the receiving part, wherein the plurality of comb-shaped support points contacts the receiving wall inner side and at least one gap is arranged between the at least one curved wall area and the receiving wall inner side after the inserting; and
soldering the tube wall of the tubular connecting part to the receiving wall of the receiving part, wherein a solder formed during the soldering is received in the at least one gap, and wherein a materially bonded and fluid-tight connection is provided between the receiving wall inner side and the at least one curved wall area based at least in part on the solder.
