“…Examilioti et al [12] investigated the role of filler wire on AA2198 alloy for aerospace applications and pointed out that it greatly reduces crack formation. Huang et al [13] gave a comprehensive explanation of the role of filler wire positioning in laser welding of AA5xxx alloys: by selecting the proper angle and stand-off distance, melting of filler wire can be greatly optimized. Concerning welding of additively manufactured component, several studies demonstrated that laser techniques allow to achieve good results on steel [14] and stainless steel [15].…”

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.
