Abstract

Residual stress classified as secondary stress that exist after all loads been removed. Residual stress can be favorable or detrimental to some components, depend on its type. Usually, tensile residual stress can cause harm to components while compressive residual stress can improve the component quality. Residual stress, either tensile or compressive present in almost all manufactured components. Both residual stress, either tensile or compressive can be found in welding components. Many researchers agreed that tensile residual stress can be found in the weld metal area, but the compressive residual stress distribution is complex. The distribution welding residual stress varies in different locations depends on welding parameters, types, sequence, component type, component materials and component sizes. This review paper provides the information of welding residual stress and their distribution. This paper can help and giving idea to researchers on planning their welding work with a minimum value of residual stress.
