In a method of welding by inertial friction, after setting a first workpiece portion into rotation, the step during which an axial welding pressure is exerted on the two workpiece portions to be welded is stopped by the contact of axial limit-stops so as to obtain a limited movement, determined beforehand, of the movable slide of the welding machine such that a length reduction DELTA L = L0-L1, then between a length L0 of the two workpiece portions in contact before welding and a length L1 after welding, has a fixed value determined beforehand. <IMAGE>
