Residual Stresses in the Welded Valve Body
2024 9th International Conference on Smart and Sustainable Technologies (SpliTech)Two-way globe valve bodies are often used in the process industry as the main valve component that carries the internal pressure. The bodies of such valves can be made by casting and, in the case of higher internal pressures, by welding. During welding, the central part of the valve body is made from a larger-diameter steel rod, and extensions in the ...

Residual stress in welded pipe
Steel in Translation, 2014In recent years, increasing attention has focused on the residual-stress distribution in welded pipe, since residual stress is often responsible for the failure of welded pipe in industrial equipment. Residual stress σres appears in each step of welded-pipe manufacture, which relies on cold plastic shaping.

The welding residual stress has a prominent contribution to the fatigue damage in deck-to-rib joints of orthotropic steel decks. To estimate the fatigue reliability of deck-to-rib joints with the combined effect of welding residual stress and stochastic ...

Use of static stress for modification of welding residual stresses
Science and Technology of Welding and Joining, 2002Previous studies have suggested that the application of stress during weld cooling could change the microstructure and residual stress state of a weld. Flat bar specimens were welded in a prestressed condition of tensile or compressive stress. The longitudinal residual stresses were found to decrease with application of tensile pre-induced stresses and

The level of welding residual stress is an important consideration in the ECA of a structure or component such as a pipeline girth weld. Such a consideration is further complicated by their variation under load and the complexity involved in the proper assessment of fracture mechanics parameters in a welding residual stress field.
