Laser ultrasonic technology for residual stress measurement of 7075 aluminum alloy friction stir welding

Applied Acoustics, 2019
Friction stir welding (FSW) is widely used in the welding of aluminum alloys for aerospace applications, because of its low energy consumption, high efficiency and good mechanical properties.

Residual Stress Measurements in Autogenous SA508 Steel Welds

Volume 6: Materials and Fabrication, Parts A and B, 2008
Engineering integrity assessments for power plant components need to account for the primary loads that arise during service as well as any residual stresses that may be associated with materials processing or fabrication. Welding operations come under particular scrutiny because they introduce substantial residual stresses.

Effect of welding sequence on residual stress and deformation of 6061-T6 aluminium alloy automobile component

Transactions of Nonferrous Metals Society of China, 2019
Four different welding sequences of double-pulse MIG welding were conducted for 6061-T6 aluminum alloy automobile bumpers by using nonlinear elastoplasticity finite element method based on ABAQUS software. The post-welding residual stress and deformation

Evaluation of Welding Residual Stress in GTAW Tubular Welds

Volume 3: Design and Analysis, 2013
The purpose of this study is to evaluate the welding residual stress of the tubular welds with welding pass and restraint conditions. For it, a heat input model for GTA (Gas Tungsten Arc) pulse welding was developed by comparing the molten pool shape and the temperature history in way of the weld obtained by FEA and experiment.

Residual Stress Prediction In Letterbox-Type Repair Welds

2007
Many researchers over the last two decades have paid attention to predict satisfactorily the residual stresses in weldments. Dong et al [1] inferred that residual stresses in weld repairs typically exhibit strong three-dimensional features, depending on both component and repair geometry. Repair welds are a common way in industry of repairing cracks or

Thermal Modifications of Welding Residual Stresses

1982
Significant changes can be made in welding residual stresses by proper welding and post-weld thermal techniques. In particular, the axial ID stresses in butt welded schedule 80 austenitic stainless steel pipes are usually tensile in the weld heat affected zone.
