Residual Stresses in Linear Friction Welded IMI550
Journal of Neutron Research, 2004Residual 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 of the welds.

Residual Stress Prediction for the Inertia Welding Process
Journal of Neutron Research, 2004Predictions 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.

Residual Stresses Due to Circumferential Welds
Journal of Engineering Materials and Technology, 1973The residual stress distribution produced by a circumferential weld between axisymmetric shells (cylinders, spheres, cones, etc.) is quite different from that due to a butt weld between two flat plates. The reason for this difference is pointed out and it is shown that the state of stress in thin-walled shells may be estimated from that in a plate ...

Residual Stress Management in Welding: Residual Stress Measurement and Improvement Treatments
Volume 6: Materials Technology; Polar and Arctic Sciences and Technology; Petroleum Technology Symposium, 2012Residual stress (RS) can significantly affect engineering properties of materials and structural components, notably fatigue life, distortion, dimensional stability, corrosion resistance etc. Residual stresses play an exceptionally significant role in fatigue of welded elements. The influence of residual stresses on the multi-cycle fatigue life of butt

Welding Residual Stresses in Tubular Joints
Materials Science Forum, 2013In spite of an increased awareness of welding residual stress threat to structural integrity, the extent of its influence on fatigue especially under multiaxial loading is still unclear and is a matter of debate. One important reason for this lack of clarities is that the determination of the initial welding residual stress field in welded structures ...

Residual stresses in welded structures
International Journal of Pressure Vessels and Piping, 2008Abstract The nature of residual stresses in welded structures is discussed in terms of their magnitude, directionality, spatial distribution, range and variability. The effects of the following factors on the residual stresses are considered: material properties, material manufacture, structural geometry, fabrication procedure, welding procedure ...

Residual Stress Evolution in Repair Welds
Strain, 2003Abstract: The aim of this paper is to study the influence of the repair procedure on the evolution of residual stress distribution in butt welds. C‐Mn steel coupon plates of 11 mm thickness were prepared, subjected to stress relief heat treatment and welded with two beads, using the gas metal arc welding process. After the deposition of two weld beads,

Redistribution of the residual welding stresses
Marine Systems & Ocean Technology, 2013This 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 ...

Welding Residual Stress and Pipeline Integrity
Offshore Technology Conference-Asia, 2014Understanding welding-induced residual stresses can help the pipeline industry to produce and install safer, more reliable and potentially more cost-efficient pipeline designs. The weld residual stresses are often found to be in the tensile stress state in parts of the weld which is well-known to have a destructive effect on the fatigue life and ...
