Abstract
In a method for regulating or controlling the conveyance speed of a wire composed of consumable material during a laser soldering or welding method, the wire is melted by a laser beam from a laser unit and is conveyed at a mean conveyance speed toward a workpiece to be processed, wherein a voltage between the wire and the workpiece is measured. A laser soldering or laser welding device carries out this method. In order to avoid at least relatively lengthy short-circuit breaking between the end of the wire and the workpiece, the conveyance speed of the wire, as a function of the measured voltage, is temporarily increased to a predetermined boost speed by increasing the conveyance speed to the predetermined boost speed when a defined voltage limit value is exceeded, and the conveyance speed is reduced again at the latest when the voltage limit value falls below.
