Description
Non-destructive testing (NDT) plays a critical role in the quality assurance of additively manufactured components. Due to the layer-wise manufacturing process, additive manufacturing can introduce process-induced defects such as porosity, lack of fusion, and residual stresses, which may significantly affect mechanical performance and structural integrity. NDT methods ideally enable the detection and characterization of such defects without impairing component functionality, thereby supporting process validation, reliability assessment, and safe industrial implementation.
Among emerging NDT techniques, laser ultrasonics is a promising candidate for both post-process quality assessment and in-line monitoring of additively manufactured components. While laser ultrasonic testing can also be employed for porosity assessment, the present study focuses on the detection and characterization of defects (voids). To this end, experimental results are presented for additively manufactured test specimens containing intentionally fabricated voids of varying sizes and depth locations. The laser ultrasonic measurements are validated through comparison with X-ray tomography (micro-CT) data. The results demonstrate the potential of laser ultrasonics for reliable defect detection and characterization in additively manufactured parts.
