Abstract

L'invention concerne un procédé de liaison et similaire qui sont appropriés pour former une liaison plus facilement que ce faisant par les seuls moyens de diffusion ou similaires. Un premier élément de liaison (11) comporte des parties d'interférence (13) qui interfèrent avec des parties en saillie (18), et ne s'ajuste donc pas dans un espace de liaison (16) d'un second élément de liaison (15). Une unité de traitement de liaison (3) d'un dispositif de liaison (1) applique une vibration sonique et/ou une vibration ultrasonique au premier élément de liaison (11). Le premier élément de liaison (11) est soumis à une oscillation de résonance et se dilate et se contracte, et s'ajuste dans l'espace de liaison (16) du second élément de liaison, et un processus de liaison est réalisé dans l'état ajusté. Ainsi, la présente invention peut être utilisée conjointement avec un procédé de liaison mécanique.
