Häufig werden zu umwelttechnischen Untersuchungen jedoch nur einzelne Schritte der Fertigung eines Produktes und nicht die gesamte Prozesskette betrachtet. Der vorliegende Artikel liefert einen Vergleich von konventionellen und additiven Fertigungsverfahren anhand eines Demonstratorbauteils unter umwelttechnischen Gesichtspunkten. Zu diesem Zweck werden die Wertschöpfungsketten der additiven Fertigungsverfahren des Laser Powder Bed Fusion und der Wire Arc Direct Energy Deposition mit einer konventionellen Fertigungsprozesskette verglichen. Hierbei kommen Energieverbrauch, CO2-Ausstoß und Abfallaufkommen als wesentliche Vergleichskriterien zur Anwendung. Im Ergebnis sind die additiven Fertigungsverfahren für das Demonstratorbauteil, in Bezug auf die genannten Kriterien als nachhaltiger zu bewerten. Der Artikel erhebt keinen Anspruch auf vollständige Übertragbarkeit, präsentiert jedoch einen Ansatz zur Analyse der Bauteilnachhaltigkeit über die gesamte Wertschöpfungskette.

Machinery requirements for this are minimal, entailing only a welding device for energy input and a guiding machine to shape the component. Though there are clear benefits to the process, such as the cost-effective technology and high deposition rates, the complex interactions involved must receive due consideration.

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.

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.
