THERMAL SPRAYING INSTRUMENT

The invention relates to a device and method for controlling the operation of a thermal spray torch (12). The inventive device and method are characterised in that an on-board camera (54) and pyrometer (70) are used to measure the properties of the jet (16) and the temperature of the deposit (24) on...

Beschreibung
Zusammenfassung:	The invention relates to a device and method for controlling the operation of a thermal spray torch (12). The inventive device and method are characterised in that an on-board camera (54) and pyrometer (70) are used to measure the properties of the jet (16) and the temperature of the deposit (24) on the part (22) and in that the correction to be made to the supply parameters of the torch (12) is deduced. Furthermore, the invention is characterised in that the corrected parameters are sent to the cabinet (30) that controls the torch (12). L'invention propose un dispositif et un procédé de contrôle du fonctionnement d'une torche (12) de projection thermique remarquables en ce que l'on mesure à l'aide d'une caméra (54) et d'un pyromètre (70) embarqués les caractéristiques du jet (16) et la température du dépôt (24) sur la pièce (22), en ce que l'on en déduit la correction à apporter aux paramètres d'alimentation de la torche (12) et en ce qu'on transmet les paramètres corrigés à l'armoire (30) commandant la torche (12).
