CRIS Current 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.
EnglishThis paper refers to the results obtained in the investiga-tion on bubbles formation in hybrid Laser-GMAWwelding. Bead on plate weldings were obtained on 8 mm thick AA6082 plates and the process parameters investigated were: GMAW current, arc transfer mode and mutual distance between arc and laser sources. Bubbles were observed by means of X-ray inspection techniques and measured exploiting an image analysis software. Finally a correlation, based on analysis of variance, between process parameters and porosity formation is proposed.
