Method for screwing of e.g. connecting ferrules to connect duct portions in civil transport airplane, involves transmitting assigned tightening torque to screwing tool, and applying transmitted torque to identified ferrule using tool

The method involves referencing parts e.g. connecting ferrules (P1, P2) and clamping rings (P3), by assigning a preset tightening torque to the parts. The part to be screwed is identified from the referenced parts using a camera (4). The assigned torque is transmitted to a screwing tool (2A) using a transmitting unit (6) via wireless links (L1). The transmitted tightening torque is applied to the identified part using the screwing tool. The tightening torque really applied to the identified part is measured. The measured torque value and references of the used tool are stored in a memory (3). An independent claim is also included for a tool for screwing of parts. - Selon l'invention, on référence préalablement une pluralité de pièces à visser (P1, P2, P3) en leur attribuant un couple de serrage propre, on identifie la pièce à visser parmi les pièces référencées (P1, P2, P3), on transmet à un outil de vissage (2A) le couple de serrage attribué à la pièce identifiée (P1, P2, P3) et on applique à cette dernière le couple de serrage attribué transmis, à l'aide dudit outil de vissage (2A).
