The additive manufacturing method offers a number of advantages such as rapid prototyping, design flexibility and unique part production. However, compared to traditional production methods, the production volume is limited. Therefore, to meet large-volume production demands, additive manufacturing is not as effective as traditional methods. In order to overcome this disadvantage, scientists are conducting research on the assembly of parts produced by additive manufacturing method. This study focuses on investigating the MIG (Metal Inert Gas) weldability of AlSi10Mg SLM (Selective Laser Melting) plate to AlSi10Mg SLM plate and subsequently optimizing the welding parameters for welding zone hardness and tensile strength. The most suitable parameters obtained in the hardness optimization of the weld zone were determined as 20.6 V, 120 A, 5356 (AlMg5). The most suitable parameters for tensile strength optimization were determined as 20.6 V, 110 A and 4047 (AlSi12). In addition to all these, 4047 filler material is thought to be the most suitable weld filler material for this study, as it provides the best tensile strength performance, offers acceptable weld zone hardness and is relatively easily accessible in the market.
