1. A method for preparing an automated welding method for a welding process, wherein a welding torch with a consumable welding wire is moved during a movement phase at a positioning speed from an actual position to a desired start position of a welding seam, which is to be produced during the welding process, and the distance of the end of the welding wire from the workpiece is bridged in that the welding wire is moved to the workpiece during a creep phase until the welding wire end contacts the workpiece, whereupon the welding process is started at the start position with ignition of an arc, wherein the creep phase is carried out at least partially during the movement phase, and the welding wire is moved in the direction of the workpiece at a first specified forward feed speed during the creep phase until a first contact of the welding wire end with the workpiece is detected, the welding wire is moved away from the workpiece after detection of the first contact, and the welding wire is then recurrently moved away from the workpiece and the contact is interrupted again in response to the detection of further contacts, and the movement of the welding wire to the workpiece until the welding wire end contacts the workpiece and movement away from the workpiece after the contact is repeated until the start position of the welding torch is reached, wherein a backward feed speed of the welding wire during the movement phase is larger than the positioning speed of the welding torch in the direction of the workpiece during the movement phase.
