1. A process for welding a conductor onto a workpiece, comprising:
providing the conductor including a first metal;
providing the workpiece including a second metal;
removing an insulation of the conductor over a predetermined length;
forming a bead in a stripped region of the conductor;
holding down the conductor on the workpiece to produce a mechanical contact in a welding region between the conductor and the workpiece, the welding region is arranged in a region of the bead;
laser welding the conductor to the workpiece at the bead in the welding region; and
after the laser welding in the welding region, laser welding the conductor to the workpiece at the bead in a further welding region, the conductor initially lies in contact with the welding region and not in contact with the further welding region when the bead is formed.
