Part for connection to at least one further part, method for connecting a part to at least one further part, and composite part

A structural element for connecting to at least one further structural element, wherein

• the structural element has at least one weld portion to be welded to the further structural element by vibratory welding, and
• the weld portion has a weld surface for connecting to the further structural element,
• the weld portion is spatially separated from a rest of the structural element by at least one vibration decoupling zone for reducing the diversion of vibration energy from the weld portion to the rest of the structural element, and
• a mid-point of the weld portion has a distance from a centroid of the structural element, in a projection perpendicular to the weld surface.

A structural element for connecting to at least one further structural element, wherein

• the structural element has at least one weld portion to be welded to the further structural element by vibratory welding and
• the weld portion has a weld surface for connecting to the further structural element,
• wherein the weld portion is spatially separated from a rest of the structural element by at least one vibration decoupling zone for reducing the diversion of vibration energy from the weld portion to the rest of the structural element, and
• a moment of inertia of the region of the structural element that is enclosed by the vibration decoupling zone, and said moment of inertia is determined with respect to an axis running through the mid-point of the weld portion and perpendicularly in relation to the weld surface is, at most, 50% of a moment of inertia of the structural element as a whole, measured with respect to said axis,
• and/or
• a mass of the region of the structural element that is enclosed within the vibration decoupling zone is at most 50% of a mass of the structural element as a whole.
