- Residual stress can be favorable or detrimental to some components depend on its type. Generally, compressive residual stress can improve the quality of the component and tensile residual stress can cause detriment to components. On welding parameters, types, sequence, component type, component materials and component sizes the welding residual stress distribution varies in different locations. Due to stress concentrations, welding imperfections and tensile residual weld stresses tubular arch bridges are at risk to fatigue problems. These type of structural bridges are composed of circular hollow section profiles welded together in tubular joints. This paper describes the determination of residual weld stresses in K-joints with the incremental hole-drilling method. The residual stress distribution can be used to determine fatigue crack behavior and fatigue lifetime more precisely. The incremental hole -drilling method is used to measure residual welding stresses on two similar K-joints. The residual stress measurements performed with Strain gauge rosettes and are attached to the test surface and with the milling guide, a small hole is drilled through the center of the strain gauge rosette. Strains at incremental depths are measured and the residual stresses are calculated according to ASTM E837-13a. This review paper provides the information of welding residual stress and their distribution tubular K-joints. This paper can help and giving idea to researchers on planning their welding work with a minimum value of residual stress.
