Claim 0:
1. A method for regulating or controlling the conveyance speed (vD) of a wire (4) composed of consumable material during a laser soldering or laser welding method, wherein the wire (4) is melted by a laser beam (L) from a laser unit (2) and is conveyed at a mean conveyance speed (vD,M) in the direction of a workpiece (5) to be processed, wherein a voltage (U) between the wire (4) and the workpiece (5) is measured, wherein, as a function of the measured voltage (U), the conveyance speed (vD) of the wire (4) is temporarily increased to a predetermined boost speed (vD,Boost), which is on average at least 50% above the mean conveyance speed (vD,M) before the increase, by increasing the conveyance speed (vD) to the predetermined boost speed (vD,Boost) when a defined voltage limit value (UG) is exceeded, and reducing the conveyance speed (vD) again at the latest when the voltage limit value (UG) falls below.
