Examining Stress Relaxation in a Dissimilar Metal Weld Subjected to Postweld Heat Treatment [PDF]

open access: yes, 2018
Dissimilar metal welds are often required in nuclear power plants to join components made from austenitic steels to those from ferritic steels, particularly in fast breeder reactor plants, in order to join the intermediate heat exchanger to the steam ...

Residual stress redistribution during elastic shake down in welded plates [PDF]

open access: yes, 2018
Residual stresses are a consequence of welding in various structures such as ships and offshore structures. Residual stresses can be relaxed or redistributed according to the load levels during operation.

Control of welding residual stress for dissimilar laser welded materials [PDF]

open access: yes, 2008
The most common problem of welding dissimilar metals (DMWs) with respect to residual stresses is the differences in the coefficient of thermal expansion and heat conductivity of the two welded metals.

On the use of the Peak Stress Method for the calculation of Residual Notch Stress Intensity Factors: a preliminary investigation [PDF]

open access: yes, 2017
Residual stresses induced by welding processes significantly affect the engineering properties of structural components. If the toe region of a butt-welded joint is modeled as a sharp V-notch, the distribution of the residual stresses in that zone is ...

Predicting fatigue crack growth rate in a welded butt joint: The role of effective R ratio in accounting for residual stress effect [PDF]

open access: yes, 2009
A simple and efficient method is presented in this paper for predicting fatigue crack growth rate in welded butt joints. Three well-known empirical crack growth laws are employed using the material constants that were obtained from the base material ...

Review on the prediction of residual stress in welded steel components [PDF]

open access: yes, 2020
Residual stress after welding has negative effects on the service life of welded steel components or structures. This work reviews three most commonly used methods for predicting residual stress, namely, empirical, semi-empirical and process simulation ...

The effect of residual stresses on the strain evolution during welding of thin-walled tubes [PDF]

open access: yes, 2011
In many applications, negative effects of residual stresses in the material stemming from the production process, are regularly encountered. These residual stresses in cold-rolled steel tubes are mainly due to two mechanisms: (i) the rolling of the flat ...

Pulsed eddy current applied to measure residual stress in welding [PDF]

open access: yes, 2018
Welding is a manufacturing process of joining components that is dominant in industries that include civil, oil and gas, automotive, etc. Although it has various benefits, welding still causes residual stresses to remain in a component after welding ...

Residual stress evaluation in API 5L X65 girth welded pipes joined by friction welding and gas tungsten arc welding

open access: yesJournal of Materials Research and Technology, 2019
The present study compared the residual stress states in friction welded pipes of API 5L X65 to those achieved by gas tungsten arc welding (GTAW). X-ray diffraction (XRD) was used to assess residual stresses.

Comparative study of evolution of residual stress state by local mechanical tensioning and laser processing of ferritic and austenitic structural steel welds. [PDF]

open access: yes, 2015
Complex thermal stresses generated in welded structures are undesirable but inevitable in fusion welding. The presence of residual stresses can be detrimental to the integrity of a welded joint.
