This disclosure relates to a method for connecting a strand element to a connection element using a re-shaping method, such as a connecting a cable lug. A system is also disclosed which comprises a pair of receiving elements having a front side with a recess and a hollow section. The hollow section is designed to accommodate a press insert having a front side with a recess. The receiving element and the press inserts are arranged in a vice. The system also comprises a clamp having a front side with a recess, which is suitable for receiving the connection element. When a pair of receiving elements is arranged, together with the press insert, around a central region of the connection element, then a re-shaping connection, such as a crimp connection, is produced between the strand element and the connection element.

The invention proposes a method for cohesive joining to a cable end (), in which method a welding tool element () is fitted on an open bundle end of individual cores () of the cable end (), welding energy is fed into the individual cores (), and the welding tool element () is removed from the bundle end. In the process, an engagement recess () can be formed in the open bundle end, an engagement pin () of the welding tool element () can engage into the engagement recess (), and at least a portion of the welding energy can be fed via the engagement recess (). A configured cable comprising individual cores () with a receiving sleeve () is also presented, wherein the receiving sleeve () has an inlet opening () for a bundle () of the individual cores (), the receiving sleeve () has an end piece () which is widened in relation to the inlet opening (), and there is, at least also in the widened end piece (), a cohesive connection between at least one subset of the individual cores () with respect to one another and/or between at least a subset of the individual cores () and the receiving sleeve ().
