Abstract

Wire and arc additive manufacturing (WAAM) has been attracting industrial attention due to its high productivity and flexibility. However, fatigue life data of WAAM HSLA steel is scarce. In this study, the mechanical properties and fatigue life of thin-walled HSLA steel parts fabricated by WAAM were assessed via non-destructive and destructive testing, providing a comprehensive analysis on this material's behaviour. The manufacturing conditions have a more pronounced effect on mechanical properties than the part's height, which seems not to influence the fatigue life of WAAM HSLA steels.
