| Abstract Scope |
Since AM is prone to the formation of defects during the building process, a fundamental requirement for AM is to find ways to assure the safety and reliability of the additively manufactured parts to become applicable in most fields. A possible solution for this problem lies in the deployment of various in-situ monitoring techniques. In this contribution, we present results of a study of L-PBF printed parts made of the superalloy Haynes 282, in which the formation of defects was provoked by local variations of the process parameters such as the laser power. These parts were monitored in-situ by thermography, optical tomography, melt pool monitoring and eddy current testing and ex-situ by computed tomography (CT) with the goal to evaluate the feasibility and prospect of the individual methods for the reliable detection of the formation of relevant defects. |
