Effect of processing parameters on the size of molten pool in GH3536 alloy during selective laser melting

Abstract

A combination of the finite element simulation and experimental measurement is proposed to study the influence of laser power and scanning velocity on the molten pool size in the selective laser melting (SLM) of GH3536 alloy. The results show that line energy density and molten pool size exhibit linear growth relationship within the scope of the study parameters. In addition, several GH3536 alloy samples are fabricated by SLM technology with different parameters. All SLM samples are used for metallographic experiment to measure the molten pool size. The result shows that experimental measurements are in good agreement with the simulation predictions.
