A method of assembling together, without welding, first and second pieces of plastically deformable material, said method comprising: in a first step, making a rim hole in the first piece, the hole having a rim with an inside diameter D2i and an outside diameter D2e; a step of making a counterbored hole having two successive diameters in the second piece, said counterbored hole having a first section of small diameter d8 and a second section of large diameter D8, the small diameter d8 being greater than the outside diameter D2e of the rim; a step of inserting said rim into said counterbored hole, an annular gap being defined between the outer annular face of the rim and the inner annular face of the second section of the counterbored hole; and a step of deforming the end portion of the rim so as to occupy at least part of the annular gap; said method comprising prior to the step of deforming the end portion of the rim, a step of inserting centering means in the rim hole, the centering means having a diameter Dc, where Dc=d8-(D2e-D2i), the axis of the centering means being maintained in a predefined reference position.
