Welding Process Impact on Residual Stress and Distortion [PDF]

Science and Technology of Welding and Joining, 2009
Residual stress and distortion continue to be important issues in shipbuilding and are still subject to large amounts of research. This paper demonstrates how the type of welding process influences the amount of distortion.

Residual Stress Prediction for the Inertia Welding Process

Journal of Neutron Research, 2004
Predictions of residual stresses in inertia friction welded Ni-base superalloys have been carried out using a commercial finite element code (DEFORM) combined with an energy balance approach and a 2D axisymmetric formulation. A coupled thermal and mechanical finite element model has been created.

The Variability in Weld Residual Stress

Volume 6B: Materials and Fabrication, 2019
Abstract Residual stresses resulting from welds are a key consideration in the design and assessment of piping and pressure vessels. As welding is a variable process, the resulting variability in weld residual stress should be accounted for in design and assessment.

Redistribution of the residual welding stresses

Marine Systems & Ocean Technology, 2013
This paper presents an experimental study of the residual welding stresses for butt-jointed steel plates. The stresses were monitored over two weeks after the removal of the welding constraints. The measurements were performed at the deposited metal, the heat-affected zone, the base metal close to the weld joint and along the plate using the X-ray ...

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, 2014
In 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.

Use of static stress for modification of welding residual stresses

Science and Technology of Welding and Joining, 2002
Previous 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

Welding Residual Stress Effect in Fracture Toughness

Journal of Nanoscience and Nanotechnology, 2019
The thickness of steel plates used for large structures has been increasing with the rapid increase in the size of welding structures. The growing capacity of large-scale ships, such as container ships, has led to an increase in the thickness and strength of steel plates for shipbuilding.

The Effects of Loadings on Welding Residual Stresses and Assessment of Fracture Parameters in a Welding Residual Stress Field

Volume 6: Materials and Fabrication, Parts A and B, 2011
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.

Residual Stresses in Linear Friction Welded IMI550

Journal of Neutron Research, 2004
Residual stresses in linear friction welded (LFW) IMI550 have been determined by means of high energy synchrotron X-ray diffraction. Specimens were studied in the as-welded, and three different post weld heat treated conditions. Mid-thickness-mid-width line scans were recorded across the weld line in the three principal directions ...
