In this study, the solidification cracking susceptibility of the weld metal of additively manufactured 316L stainless steel was investigated. Laser powder bed fusion was employed to fabricate rectangular specimens with a thickness of 4 mm, and Trans-Varestraint tests were performed to evaluate the weldability of the specimens. Subsequently, the maximum crack lengths were measured and used as indices of susceptibility. The results showed that the weld metal of additively manufactured 316L stainless steel had higher susceptibility to solidification cracking than that of conventional wrought 316L stainless steel. The high susceptibility was considered mainly due to the primary austenite solidification mode in the weld metal of the additively manufactured specimen having a relatively higher content of nitrogen.
