The invention relates to a method and an apparatus (10) for automated servicing of a torch head (12) comprising at least one contact tip (20) and a nozzle (26) surrounding the at least one contact tip (20). In a first servicing device (32) the torch head (12) is contact-freely cleaned in an assembled state of said at least one contact tip (20) and said nozzle (26). A second servicing device (34) is used for applying a torch head treatment agent (42) to at least a portion of the surfaces of said at least one contact tip (20) and said nozzle (26). The operation of the first servicing device (32) and the second servicing device (34), respectively, is started by a control unit (50) after the torch head (12) has been transferred to a corresponding servicing position. The torch head treatment agent may include between about 5 and about 50 percent-by--weight of boron nitride as a torch head treatment agent for servicing of a welding torch head.

L'invention porte sur un procédé et sur un appareil (10) pour un entretien automatisé d'une tête de chalumeau (12) comportant au moins une pointe de contact (20) et une buse (26) entourant la ou les pointes de contact (20). Dans un premier dispositif d'entretien (32), la tête de chalumeau (12) est nettoyée sans contact dans un état assemblé de ladite ou desdites pointes de contact (20) et de ladite buse (26). Un second dispositif d'entretien (34) est utilisé pour appliquer un agent de traitement de tête de chalumeau (42) à au moins une partie des surfaces de ladite ou desdites pointes de contact (20) et de ladite buse (26). Le fonctionnement du premier dispositif d'entretien (32) et du second dispositif d'entretien (34), respectivement, est démarré par une unité de commande (50) après que la tête de chalumeau (12) a été transférée à une position d'entretien correspondante. L'agent de traitement de tête de chalumeau peut renfermer entre environ 5 et environ 50 pourcent en poids de nitrure de bore en tant qu'agent de traitement de tête de chalumeau pour l'entretien d'une tête de chalumeau soudeur.
