CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn this study, we present an innovative real-time laser welding monitoring technique employing the correlation analysis of the plasma plume optical spectra generated during the process. In order to look for a relationship between optical signals and welds quality, the influence of the experimental conditions on the correlation plots are also investigated. The correlation analysis results allow to evaluate the quality of the welds, through an on-line detection of common defects, such as oxidation or lack of penetration, with an excellent spatial resolution.
