A method for controlling the quality of an industrial laser process.

摘要

Method for controlling the quality of industrial processes of laser, comprising the steps of: focusing a laser beam in a treatment area, detecting the radiation emitted by the treatment area by means of detection photodiode, and processing the signals emitted by said detection means, characterized in that said step of processing signals includes the following operations: - calculating the transform coefficients of discrete wavelet with respect to a plurality of scale values, thus obtaining a plurality of transformed signals (W ); - processing said transformed signals (W) so as to obtain one or more values ​​(V) representing the process quality, so that the quality control process can be carried out only from the processed signal said manner, without the need for a comparison with a predefined reference signal corresponding to a good quality welding.
