| Abstract Scope |
Nowadays, structural parts for the aero industry are milled from solid blocks, which leads to a buy-to-fly-ratio of 25:1. A promising possibility to efficiently improve the ecological footprint is wire arc additive manufacturing (WAAM). By this cost-efficient technique, it is feasible to decrease the lead-time and reduce the material loss to a buy-to-fly ratio of 7:1. Test samples with different welding parameters and post-process heat-treatments were produced and mechanically tested. Subsequently, the achieved microstructure was characterized using SEM and EBSD. As-built state specimens showed similar strength compared to conventionally produced samples. Due to WAAM intrinsic heat-treatment, a stress-relieve treatment was found to be negligible. Currently, the fatigue behaviour and evolution of residual stresses with respect to the welding parameters are investigated. Hence, WAAM Ti-64 fulfils the required mechanical properties and thus opens a promising way for the efficient production of high quality titanium parts. |
