Beschreibung
Zusammenfassung:	A laser machining head has at least one channel in a welding nozzle, through which welding filler material is deposited. At least one of the following features i) to iv) is implemented: i) a wire-shaped welding filler material is supplied through the channel into the laser beam via a drive motor. An electric current in the drive motor is measured, and the feed movement of the filler material is influenced by the measured current; ii) a strain gauge is attached to a housing or the welding nozzle, where by the strain gauge a termination of the machining process is initiated when a measurement signal value is reached; iii) a termination of the machining process is initiated by a contact arrangement on the housing; and/or iv) an electronic camera is used to monitor the supply of welding filler material, and the feed movement of at least one filler material is influenced.
