Abstract:

We present our X-ray high-resolution sintered and additive manufactured parts in-line NDT investigations based on various mini|microfocus X-ray set-ups. We are introducing also our latest development, an industrial combined X-ray scanner and a Laser-based 3D profiler machine for sintered parts in-line NDT control in one short pass. With the new equipment design we combined two advanced control techniques: the Laser-based profiler for getting the parts 3D shape measurement with 2-3% accuracy, followed by an X-ray digital imaging system for parts internal defects identification, based on a minifocus X-rays source and a TDI (Time Delayed Integration) X-ray detector. The system is able to compute also the sample’ local density for sintered ceramic ballistic plates and to NDT analyse the transmission digital Xray images at a pixel size of 60 microns for detecting the internal defects.
