To achieve this, 186 possible causes of risk were analyzed and the five most critical risks were discussed in detail. Four significant risk factors were identified in the construction process. The fifth risk relates to the shielding gas flow. This is only one influencing factor among the welding parameters, which have strong interactions with each other. Therefore, their relationships should be analyzed on the basis of numerous tests.}, language = {en} } @incollection{GruegerFischerWoll, author = {Gr{\"u}ger, Lennart and Fischer, Tim Sebastian and Woll, Ralf}, title = {Investigation of the Wire Arc Direct Energy Deposition-Process and Possible Interactions}, series = {Advances in Manufacturing IV}, volume = {2024}, booktitle = {Advances in Manufacturing IV}, editor = {Gapiński, Bartosz and Ciszak, Olaf Stanisław and Ivanov, Vitalii and Machado, Jose Mendes}, edition = {4}, publisher = {Springer Nature Switzerland}, address = {Cham}, isbn = {9783031564659}, issn = {2195-4356}, doi = {10.1007/978-3-031-56463-5_14}, pages = {176 -- 194}, abstract = {The Wire Arc Direct Energy Deposition (WA-DED) process is highly regarded as part of additive manufacturing. Compared to other additive manufacturing processes, it is characterized above all by its high deposition rate and low system costs. Despite many years of experience in the build-up welding process, WA-DED still holds a number of challenges in terms of process stability. This article analyses the interactions in the WA-DED process. To this end, the process was visualized and described with the help of Structured Analysis and Design Technique (SADT). Building on this, a process Failure Mode and Effects Analysis (FMEA) was presented to identify and priorities risks. Finally, the results of the Taguchi tests were analyzed and visualized. The results illustrate the strong interactions between the influencing factors. These have a material-specific effect on the production results. Each new material composition therefore requires a systematic analysis in order to determine quantitative correlations. In future, these can be supported by machine learning approaches.}, language = {en} }
