Abstract
A method of fastening at least one second object to at least one first object, wherein mechanical vibration acts from a sonotrode on the second object to fasten the second object to the first object. Between the sonotrode and the second object, an auxiliary sheet is placed, for example of paper. After the vibration stops, the auxiliary sheet is displaced relative to the sonotrode for a next fastening step.

A method of fastening a second object to a first object, comprising the steps of:
- providing the first object comprising a first attachment surface;
- providing the second object being of a metallic or ceramic material or of a fiber composite material;
- placing the second object relative to the first object;
- placing a sonotrode relative to the second object;
- placing an auxiliary sheet between the sonotrode and the second object;
- and
- while the sonotrode is in contact with the auxiliary sheet and the auxiliary sheet is in contact with the metallic or ceramic material or the fiber composite material, causing mechanical vibration to act from the sonotrode on the second object via the auxiliary sheet to locally bond the second object to the first object;
- wherein the auxiliary sheet is made of an auxiliary sheet material containing at least one of paper and of cardboard.
