  We use single track laser melting experiments and simulations on Inconel 625
to estimate the dimensions and microstructures of the resulting melt pools. Our
work is based on a design-of-experiments approach which uses multiple laser
power and scan speed combinations. Single track experiments generate melt pools
of certain dimensions. These dimensions reasonably agree with our finite
element calculations. Phase-field simulations predict the size and segregation
of the cellular microstructures that form along the melt pool boundaries for
the solidification conditions that change as a function of melt pool
dimensions.
