The gas tungsten arc welding (GTAW) process is an excellent way of performing quality hard- -facing applications. The residual stresses and distortions are encountered in hard-facing. There are several methods to decrease residual stresses. Changing the welding pattern, changing thickness and preheating can be mentioned for this purpose. In this work, the influence of the welding pattern, plate thickness and preheating was investigated. The temperature distribution with the same welding conditions was used for validation of the numerical model. The total deformation in a 2mm plate was 15 times higher than in a 6mm plate with the same welding conditions.
