The invention relates to a device and method for controlling the operation of a thermal spray torch (). The inventive device and method are characterized in that an on-board camera () and pyrometer () are used to measure the properties of the jet () and the temperature of the deposit () on the part () and in that the correction to be made to supply parameters of the torch () is deduced. Furthermore, the invention is characterized in that the corrected parameters are sent to the cabinet () that controls the torch ().

Thermal spraying instrument

The invention relates to a device and a method for control of the operation of a thermal projection torch (), characterized in that the characteristics of the jet () and the temperature of the deposit () on the piece () are measured by means of a camera () and a combined pyrometer (). The correction to be made to the supply parameters of the torch () are deduced therefrom and the corrected parameters are transmitted to the unit () controlling the torch ().
