Abstract
Process for mfr. of metal assemblies which have >=2 elements comprises assembling two metal elements of which one is two parts produced from a single piece and is connected at one point so that the two parts have a free end which is remote from the connection point and at which the second element comes into contact when it is in its posn. for assembly with the first element. The two elements are joined by diffusion by pressure, or by rolling the first element through its free end onto the second element. The process is applied to aircraft parts comprising metal plates with spacers and is designed to reduce fatigue in the parts.
