Abstract: A biomaterial is a matter that has been bring about to interact with biological systems for a medical purpose, either a therapeutic such as treatment, enhance, repair, or replace a tissue function of the body or a diagnostic one. Several metals, ceramics and polymers used as biomaterials. Metals are nominated for biomedical applications due to its properties such as biomechanical characteristics, surface finishing characteristics. Moreover, finite element models provide a detailed insight of several issues where experimental investigations not enough to understand. In the present work, a three-dimensional thermal model based on conduction heat transfer is developed to predict the thermal behavior during arc welding of austenitic stainless-steel plates of different thickness. The novelty of the present work is modeling of dissimilar plate thickness joining using finite element method. Moreover, double ellipsoidal power density model of Gaussian distribution is selected along with appropriate incorporation of material responses as a function of temperature for carrying out thermal analysis. Based on numerical results, it is determined that the developed process model is highly efficient in estimating thermal responses such as temperature history, weld profile and weld dimensions for dissimilar thickness plates joining.
