A method is provided for producing a component connection. The method includes the following steps: providing a first component, providing a first ball, pressing the first ball against the first component by a sonotrode, vibrating the first ball by the sonotrode such that material of the first ball and/or material of the first component melts, and the first ball is welded to the first component, providing a second ball, pressing the second ball against the first ball by the same sonotrode or another sonotrode, and vibrating the second ball by the same sonotrode or the other sonotrode such that material of the second ball and/or material of the first ball melts, and the second ball is welded to the first ball.

A manufacturing method for a joined body, includes: bringing a first member and a second member into contact with each other, at least one of the first member and the second member being made of thermoplastic resin, and the second member having a recessed portion on a joining surface to be joined to the first member; and welding the first member and the second member together, including welding a contact portion of the first member and the second member by melting the thermoplastic resin by frictional heat generated in the contact portion by relative movement of the first member and the second member, in a state in which the first member and the second member are in contact with each other.

A device (1) for automated connection of two components (25, 27) in joint region (29) is proposed. The device (1) has a rotating winding device, especially a circle-segment-like rotor (3), which is arranged to guide a cloth tape (23) along winding paths (26) and to create a wound joint connection in the joint region (29).

A method is provided for producing a component connection. The method includes the steps of: providing a first component that is made of a thermoplastic plastic material at least in the region of a portion of the surface thereof; providing a ball that is made of a thermoplastic plastic material in at least one region of the surface thereof; pressing the ball on the first component such that the thermoplastic plastic material of the ball comes into contact with the thermoplastic plastic material of the first component; vibrating the ball using an ultrasonic sonotrode and welding the ball with the first component; providing a second component having a through hole; bringing the second component to the first component in such a way that the ball projects at least into the through hole of the second component or a portion projects to a certain extent through the through hole; clipping a clip element to the ball, wherein the clip element projects beyond the through hole and joins both components to one another in an interlocking and/or force-locked manner.

A welded joint between at least one metal material element and at least one thermoplastic material element is obtained by pressing the elements against each other while applying heat. Contact surfaces of the metal material, which are in contact with the thermoplastic material, are provided with uneven surface portions having a distribution of asperities. With heat applied, the thermoplastic material fills spaces between these asperities and maintains this configuration after subsequent cooling, thereby improving strength of the joint. The uneven surface portions are obtained in a preliminary forming step of the metal material in a press mould, which is configured with a forming surface for generating the uneven surface portions by mechanical deformation and/or with a device for guiding a laser or electron beam. By this technique, hybrid components are obtained made of one or more elements of metal material between which a shaped component of thermoplastic material is interposed.
