Abstract. One of the most critical factors to be taken into consideration in laser welding of aluminum alloys is the formation of pores in the fused zone, which depends strictly on the semi-finishing format of the parent sheets. According to these considerations the present paper deals with welding of AA6082 sheets with additively manufactured AlSi10 ones in a configuration that is typical for the production of casings for batteries for the e-mobility field. In order to understand the role of process strategies on weld bead quality, both autogenous welding and welding with filler wire are investigated and the eventual benefits of applying a wobbling beam shaping is also considered. For any of the above-mentioned strategies, the role of process parameters, such as laser power, welding speed, filler wire speed and wobbling, is underlined, with particular reference to the formation of pores and defects.
