“…Of all the solid-state welding processes evaluated, FSW is by far the most widely used process for joining AM-manufactured Al alloys [37,[55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70]. For this process, only studies were found evaluating the weldability of parts produced by the PBF-LB process.…”

“…This heightened presence is attributed to the expectedly greater plastic deformation on the advancing side during the welding process [56]. The influence of the addition of 2 wt% nAl2O3 to the AlSi10Mg during the PBF-LB manufacturing process was evaluated by two studies [58,59]. The obtained results show an increase in the porosity level from 0.07 to 0.10% at low heat input and from 0.06 to 0.16% at high heat input [58].…”

“…Manipulation of the chemical composition had a negative effect on the mechanical strength of the welds, resulting in a decrease of the UTS from 238 to 146 MPa at low heat input and from 240 to 135 MPa at high heat input [58]. The influence of the addition of 2 wt% nAl 2 O 3 to the AlSi10Mg during the PBF-LB manufacturing process was evaluated by two studies [58,59]. The obtained results show an increase in the porosity level from 0.07 to 0.10% at low heat input and from 0.06 to 0.16% at high heat input [58].…”

Additive manufacturing (AM) processes are playing a significant role in several industrial sectors such as construction and machine building industries, involving a wide variety of metallic materials. Among these, the AM of aluminium alloys has developed significantly over the last decade, mainly through Powder Bed Fusion (PBF) and Directed Energy Deposition (DED) processes. Despite the many advantages of AM technology, some large or complex products cannot be produced entirely without the use of conventional manufacturing and joining processes, generally for financial or operational reasons. In this way, the ability to join conventionally and additively manufactured components or parts represents a crucial step towards their future use and the consolidation of conventional and additive manufacturing technologies. Despite the growing interest in AM technologies, there is still a significant lack of information on the joining of conventionally and additively manufactured components. The present work proposes a first review of the literature evaluating the weldability of AM aluminium alloys. The focus is on the use of fusion and solid-state welding processes and analysing the achieved microstructural evolution and mechanical properties. A clear relationship is observed between the AM technology used to produce the part, and the physical principles of the joining process. In addition, the gaps in the literature are highlighted to enable focused future work.
