Abstract: Welding is one of the most important phenomena required in day to day activities like construction, machining, etc. Therefore, it becomes important to choose optimal parameters for its process since non-efficient selection of its parameter can result in failure of activities it is associated with. Studies show that stress concentration zones, are those where maximum stress is generated. In case of welding, these zones are weld root and weld toes. In order, to get accurate results fine meshing becomes necessary. In the current study, a 3-D structure i.e., two perpendicular plates are connected to a reclining plate by welding, precisely fillet weld. Finite element analysis has been conducted on the above-mentioned structure. Mechanical behavior has been studied for various values of fillet radius and load values. Fillet radius and load (on right as well as left hand side) has been varied from 3mm-9mm, with a difference of 2mm and 100N-10000N, in the multiple of 10N respectively. Continued increase in load, in turn, accelerates the stress, in the weld root and toes. The relation between stress, strain and total deformation with fillet radius is inversely proportional.
