- Abstract
The article discusses a research project called "nodularWELD" that investigates the fatigue behavior of welded thick-walled nodular cast iron components used in heavy industry and wind energy turbines. The study examines the effects of local material defects on the lifetime of these components and explores the possibility of repair welding. The research project examines different welding fillers and conducts fatigue tests to assess the usability of repair-welded nodular cast iron. The findings show a reduction in fatigue strength for all materials in the welded condition, with the highest loss observed for EN-GJS-450-18. The research suggests that welding for repair purposes may not be feasible for certain applications. The document also includes a list of nomenclature, references, and acknowledgments to the funding source and project partners.
