One of the additive manufacturing methods is deposition with direct energy, which is used to produce and repair complex parts in industries. This method includes a set of variables that significantly affect the geometry of deposited layers. In this research, the effect of power and laser scanning speed on the geometrical features (width, height, and wetting angle) of Inconel 718 clads on 316 stainless steel substrate has been investigated. Based on the experimental results, the mathematical equations for the relationship between the crucial variables of the process and the geometry of the clads were established by the method of multiple regression analysis, and the results showed that the measured data is consistent with the predicted one. Based on the equations, it was predicted that the laser scanning speed has a decreasing effect on all the investigated geometric features of the clads while the laser power has an increasing effect on the width and height of the clads and a decreasing effect on the wetting angle.
