FE-SEM images of the microstructure at 0.8 mm of the laser spot diameter: (A) Noritake Super alloy, (B) Bellabond plus alloy, and (C) VeraBond 2V alloy specimens. Boundary area of the laser irradiation: ((A)-1), ((B)-1), and ((C)-1); higher magnification view of the box in magnification: (b) hot tear area marking.

FE-SEM: field emission scanning electron microscopy; HAZ: heat-affected zone.
