Abstract
The invention relates to a welding device () having a welding torch (), a feeder () for feeding a melting filler material () at a feed rate (v) to a weld (S), where the filler material () is melted with the aid of an electric arc (L), and a pre-heater () for heating the filler material () upstream of the weld (S) by means of a laser beam () having a laser power (P) and generated in a laser device (). For space-saving and safe heating of the filler material () upstream of the weld (S), the pre-heater () includes a feed channel () for the filler material (), and at least one deflector () is attached to the pre-heater () for deflecting the laser beam () to the filler material () in such a way that the laser beam () strikes the filler material () inside the feed channel () of the pre-heater ().
