The method of mechanically coupling two parts (10, 12), a first (12) of the two parts being formed from a first conductive material and with a first contact area delimiting at least one recess (22) in the first part, a second (10) of the two parts being formed from a second conductive material incompatible with welding with the first conductive material and with a second contact area (16) forming at least one projection of the second part (10) having a dimensional interference with the first contact area (22), involves carrying out the following steps: first, bringing the two parts (10, 12) together in such a way that the first and second contact areas (16, 22) come at least partially into contact with each other; then fitting the second part (10) into the first part (12) by means of a relative movement parallel to an insertion axis while causing an electric current to flow between the two parts (10, 12) and sufficient heating by Joule effect to bring at least one of the first and second contact areas (16, 22) locally to a temperature greater than or equal to a melting temperature, causing a radial deformation of at least one of the first and second contact areas (16, 22). |
