The present application describes herein a system (Fig 1) and a method (Fig 2) for monitoring laser welds (6), by using sensor means (8) and processing means (9) which are extracting characteristics of the signal coming from sensor means (8) and classifying them to give an indication of the quality of welds, enabling on-line and real-time detection, during execution of the welding process, of possible welding defects, such as: insufficient depth of penetration; misalignments of the coupling during assembly of the pieces to be welded; presence of porosities; reductions in the level of power of the laser source; or drops in power of the laser source.

Abstract
The present application describes herein a system (Fig 1) and a method (Fig 2) for monitoring laser welds (6), by using sensor means (8) and processing means (9) which are extracting characteristics of the signal coming from sensor means (8) and classifying them to give an indication of the quality of welds, enabling on-line and real-time detection, during execution of the welding process, of possible welding defects, such as: insufficient depth of penetration; misalignments of the coupling during assembly of the pieces to be welded; presence of porosities; reductions in the level of power of the laser source; or drops in power of the laser source.Pubblicazioni consigliate
