Details
Laser Powder Bed Fusion (L-PBF) Additive Manufacturing (AM) is an effective method for quickly producing smaller, complex parts. Due to the manufacturing method used, ultrasonic velocity anisotropy effects measurement capabilities for crack detection and sizing using UT. A study was performed to determine the cause of the sound velocity anisotropy for two materials (A600 and 304SS) that could be applied to more materials to ensure consistent sound properties and avoid costly post fabrication processing. The presentation will step through each phase of the study including results and specific AM build parameters that effect the anisotropy.
