Its high mechanical and chemical properties make this material a focus of interest for additive manufacturing because IN718 is expensive, and a heat treatment post-manufacturing is typically needed. This greatly increases costs and production time, with a loss of material due to machining of the material blocks that can be avoided with additive manufacturing by providing material only where needed. For the Robotic Friction Stir Welding (R-FSW) a tool with high performance is demanded. It is because the tool is inserted and moved forward between the two work pieces to join. Frictional heat is generated between the wear-resistant tool and the two workpieces. This means that the tool material is subjected to high temperature, normal oxygen conditions and high mechanical stress. Furthermore, the tool's design usually has to change very often depending on the type of material to be welded and the thickness. In this work, IN718 tools for the R-FSW process have been additively manufactured with optimized parameters under high manufacturing speed conditions and with the advantages of using metal wire. As built and heat-treated conditions heat have been microstructural and mechanically analyzed. Finally, different tool designs of the same IN718 DED-wire manufactured material have been tested in several friction stir welds, analyzing their behavior and the relation with the successful welds. The optimal thermal status and design for the IN718 FSW tools has been determined.
