the additive manufacturing methods. Particularly in industry, the product
sensitivity and cost problems in the final product output have played an
important role in the development and emphasis of this method. However, there are
disadvantages arising from the parameters applied in the method of laser metal deposition.
One of these disadvantages is residual stress. The residual stress is the
effect of the tension-compression forces within the material due to heating and
cooling speeds during the production. In this study, effects of the process
parameters used in laser metal deposition method on the elimination of the
residual stress problem and the quality of the product to be obtained were
analyzed by the finite element method and the thermal results were compared. Simufact
program was used for this study. After being transferred into a 3D design
module, changes are made on the values other than the standard parameters and
the analyzes are made and the effects on the residual stress are determined. In
this method, Simufact program allows analysis of laser speed, layer thickness
and temperature parameters. For the analysis of this study, the laser velocity
was chosen from the method parameters and the results of the analysis were performed
to investigate the effect of the laser velocity. </span> </p> <p> <br /> </p>}
