Single-track laser scan cross-sectional micrographs on IN625 and IN718 bare plates with melt pool depth and width measurements
Single-track laser scans were produced with Yb-fiber lasers on bare plates of IN625 and IN718 using three different laser powder bed fusion machines. The laser power, scan speed, and laser spot  diameter varied. Tracks were cross-sectioned and metallographically prepared. Optical micrographs were taken on etched …
