Additive manufacturing in steel construction: process and manufacturing strategies in wire and arc additive manufacturing
Benedikt Waldschmit, M.Sc.
The idea of fully automated manufacturing of steel components has been around for some time. Wire and Arc Additive Manufacturing (WAAM) offers a process which, in addition to the production of individual structures in open construction spaces, enables a significantly higher application rate than conventional additive manufacturing processes.
As part of the research at IfSW, an automated process for the inline surface finish of individually buildup-welded structures is to be developed by combining additive and subtractive process components.
In cooperation with the GMSS, the ISM+D at the TU Darmstadt and spannverbund GmbH, the manufacturing process is being investigated in terms of technical feasibility and economic efficiency in a research project funded by the ZIM.

Additive manufacturing is becoming more and more prominent in the construction industry. In steel construction, a process using arc welding, so-called Wire Arc Additive Manufacturing (WAAM), is a promising manufacturing method. Especially for larger components, a sufficiently high deposition rate is crucial. In addition to knowledge of suitable welding parameters, knowledge of the influence of cooling processes on the manufacturing and material properties of printed structures plays a decisive role. The Department of Steel Construction has two welding robots for researching the technology and its application.

Die Additive Fertigung gewinnt in der Baubrache mehr und mehr an Bedeutung. Im Stahlbau ist das Verfahren mittels Lichtbogenschweißen, das sog. Wire + Arc Additive Manufacturing (WAAM) eine aussichtsreiche Fertigungsmethode. Gerade für massive große Bauteile ist eine ausreichend hohe Auftragsrate entscheidend. Damit einher geht der Auftrag mehrerer Schweißlagen nebeneinander. Das Fachgebiet Stahlbau verfügt zur Erforschung der Technologie und deren Anwendung über zwei Schweißroboter.
