DEVELOPMENT OF MULTI-MATERIAL COMPONENTS VIA ROBOTIC WIRE ARC ADDITIVE MANUFACTURING

Additive manufacturing technologies are applied in different industrial fields. It is possible to produce 3D parts in complex form at a lower cost with faster production capability using additive manufacturing compared to traditional subtractive manufacturing. Robotic welding-based wire arc additive manufacturing (WAAM) is a novel additive manufacturing technology which offers various solutions. Many products can be produced through the additive manufacturing in the fields of defense, aerospace, and automotive industries. In this study, multi-material metallic parts were produced by depositing ferritic ER 70 S-6 and stainless steel ER316L welding wires using robotic WAAM technology. Detailed microstructural analysis and hardness tests were conducted on the manufactured samples including interfaces between two different materials. Characterization of Fe-austenite weld interfaces has shown the presence of hard phases due to migration of hardening elements. The microhardness examination revealed that the highest hardness values are recorded at the bimetallic interface due to Fe and C migration through the interface layer.
