INVESTIGATION OF LASER METAL DEPOSITION METHOD BY FINITE ELEMENT ANALYSIS: LASER SPEED EFFECT ON THIN WALLED GEOMETRY BUILDING

Abstract

Laser metal deposition method has emerged as one of 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.
