An Overview of Fillet Weld Joints Subjected to Tensile and Compressive Loads

Mechanical assemblies and parts that are in service may be subject to high stresses and different types of loads such as fatigue loads, tension loads, compression loads. In this study, finite element analysis software, ANSYS, is used for a parametric study to research the effect of weld toe radius in fillet welded joint on compression strength and tensile strength. In metal constructions, machine assemblies, shipbuilding and other heavy industries, fillet joint is a widely used structural member. There are different types of loads acting on the fillet weld joints. There are various application of fillet weld joints .We can use fillet weld joints in steel bridge girder, building structures, machine assemblies etc.When vehicles are going above steel bridge girder, it will be subjected to various types of loads such as tensile loads, compressive loads, combination of tensile and compressive loads, fatigue loads etc Stress concentrations usually occur at structural geometry discontinuities, e.g. weld toes, and crack-like defects. These stress concentration sites may serve for crack initiation and cracks that are propagating may lead to failure of weld joint. In the present work, I did the analysis and compared the effect of weld toe radius on compression strength, tensile strength of fillet weld joints under two cases and also experimental validation of result.
