Thermal spraying instrument

摘要

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 ).
