Generative Fertigung von Verdichterschaufeln einer Blisk: Drahtbasiertes Laserauftragschweißen für eine ressourceneffiziente Produktion

Additive manufacturing allows for complex, individualized and customized geometries. With technologies such as wire-based laser deposition welding, it is also possible to make production more resource-efficient. For instance, this technology helps to produce rough geometries of compressor blades for turbo machinery by depositing layers on a substrate. It substitutes conventional roughing strategies by milling and enables a significant cost reduction. This paper describes the new manufacturing technique in the context of metallographic examination using a demonstrator
