A device and method for producing a component are provided. The device or method includes steps or units for providing a first component element having a recess in or on a first surface of the first component element, and for positioning a second component element in the region of the recess. The device or method also includes a step or unit for pressing the first component element and the second component element together, and as a result forming a material fit, positive fit and/or non-positive fit between the first and the second component elements at least in the region of the recess. The positioning and the pressing can be carried out or are carried out functionally, in particular, spatially and/or temporally, in terms of equipment, separately from each other.

A coupling device couples, using a coupling member, a first plate of a first metal to a second plate of a second metal. A power source is connected to first and second electrodes. A driver moves the first and second electrodes relative to the coupling member and the first and second plates. A controller controls the power source and the driver to electrify the coupling member and the first and second plates under pressure. The coupling member includes a third metal approximately identical to the second metal. The first metal has a melting point lower than melting points of the second and third metals. The coupling member includes a pilot portion that is located about a center of a flat surface of a body of the coupling member and that protrudes in an extending direction. The flat surface has discharge grooves radially extending from the pilot portion.

A component combination of at least two components, which are joined at at least one joint, is provided. The component combination includes a first component, wherein a first joining element having a supporting section is pressed into a passage hole in the first component at the joint, and includes a second component, in which a fastening receiving section is formed at the joint, wherein the first joining element also has a fastening section, which engages in the fastening receiving section of the second component in a form-fitting and/or force-fitting manner. A method for producing the component combination is also provided.

The invention relates to a method for connecting at least two component layers by means of a connection element. the invention to provide a particularly advantageous method for connecting at least two component layers lying on top of each other through the creation of a pilot hole in at least one cover layer. The pilot hole in the form of a through hole is made in the at least one cover layer using only a plasma jet, which cover layer is at least temporarily held in place on the base layer. Holding the cover layer and the base layer temporarily fixed to each other will allow the connection element to be placed at the same position in the base layer where the pilot hole is made. Sufficiently large layers can thus be kept in a fixed position relative to one another solely using their weight and friction.

A method for undetachably introducing a guiding aid element into at least one joining location of at least one component is provided. The method includes the acts of: a) perforating the at least one component at the at least one joining location in a first press stroke of a tool press, wherein a preliminary hole is formed at the at least one joining location; b) inserting a joining aid element into the at least one preliminary hole; and c) pressing the at least one joining aid element with the at least one component in a subsequent press stroke or working step to form a material-bonding, form-fitting and/or force-fitting connection between the at least one component and the at least one joining aid element. A component and a composite component produced by such a method are also provided.
