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. ## Claims ### Claim 1 A method for undetachably introducing an auxiliary joining element into at least one joint of at least on component, the method comprising the acts of: a) punching the at least one component at the at least one joint in a first press stroke a tool press, wherein a pilot hole is formed at the at least one joint; b) inserting an auxiliary joining element into the pilot hole; and c) pressing the auxiliary joining element together with the at least one component in subsequent press stroke or work step in order to form a cohesive, form-fitting and/or force-fitting connection between the at least one component and the auxillary joining element, wherein a plurality of pilot holes are formed in the act a), an auxiliary joining element inserted into each of the plurality of pilot hole in the act b), all of the auxillary joining element inserted into the plurality of pilot holes are pressed together with the at least one component in the act c), wherein the auxiliary joining elements are thicker than the at least one component so that the auxiliary joining elements project beyond at leas one longitudinal surface of the at least one component, at least one of the plurality of pilot holes is provided at both hole edges with chamfer, and the auxiliary joining element is in the form of am metal slug. ### Claim 2 (depends on 1) The method according to claim 1, wherein the act b) is carried out in a second press stroke, which is carried out between the first press stroke of the act a) and the subsequent press stroke or work step of the act c). ### Claim 3 (depends on 2) The method according to claim 2, wherein further component processing takes place in the first press stroke, the second press stroke and/or the subsequent press stroke. ### Claim 4 (depends on 1) The method according to claim 1, wherein the act b) and the act c) are carried out in a common press stroke. ### Claim 5 (depends on 1) The method according to claim 1, wherein further component processing takes place in the first press stroke, the second press stroke and/or the subsequent press stroke. ### Claim 6 (depends on 1) The method according to claim 1, wherein the pilot hole is provided at both hole edges with a chamfer, and the auxiliary joining element is in the form of a metal slug. ### Claim 7 (depends on 6) The method according to claim 6, wherein the pressed auxiliary joining element is connected to the at least one component in a form-fitting manner by an undercut on both sides. ### Claim 8 (depends on 1) The method according to claim 1, wherein the pressed auxiliary joining element is connected to the at least one component in a form-fitting manner by an undercut on both sides. ### Claim 9 (depends on 8) The method according to claim 8, wherein the auxiliary joining element is a steel slug, and the at least one component is made of a lightweight material. ### Claim 10 (depends on 1) The method according to claim 1, wherein the auxiliary joining element is a steel slug, and the at least one component is made of a lightweight material. ### Claim 11 (depends on 1) The method according to claim 1, wherein the at least one component is a vehicle body component or a vehicle body attachment part.
