Beschreibung
Zusammenfassung:	The soldering device comprises: blank holder elements for holding a tape (5) on a surface of an electric busbar (3), where the blank holder elements are arranged one behind the other in series along a soldering line; and an induction antenna having a current path extending along the soldering line for an electrical alternating current, where the electrical alternating current is guided along the current path in such a way that it produces a magnetic alternating field in the soldering line and/or in an environment of the soldering line. The soldering device comprises: blank holder elements for holding a tape (5) on a surface of an electric busbar (3), where the blank holder elements are arranged one behind the other in series along a soldering line; and an induction antenna having a current path extending along the soldering line for an electrical alternating current, where the electrical alternating current is guided along the current path in such a way that it produces a magnetic alternating field in the soldering line and/or in an environment of the soldering line. The current path extends along portions of the soldering line, where the portions are arranged one behind the other in series in such a way that the magnetic alternating field in one of the portions of the soldering line is present in a phase opposite to the magnetic alternating field in other portions of the soldering line. The current path of the induction antenna comprises: a first portion that extends on a first side of a soldering plane, in which the soldering line lies in a distance to the soldering plane along one of the portions of the soldering line from which one of the portions of the soldering line is separated by an air gap; a second portion that extends on a second side opposite to the first side of the soldering plane in a distance to the soldering plane along other portions of the soldering line from which the other portions of the soldering line is separated by an air gap, where an end of the first portion of the current path is connected with an end of the second portion of the current path in such a way that the first and second portions of the current path are electrically switched in series, and the electrical alternating current in the first portion of the current path is present in the phase opposite to the electrical alternating current in the second portion of the current path; a third portion that extends on a first side of a soldering plane in a distance to the solde
