Abstract

This 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.
