RISResidual Stress Distribution in a Dissimilar Weld Joint by Experimental and Simulation Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dissimilar welding between carbon steel and stainless steel is widely used in power plant. A lot of stress corrosion cracking (SCC) have occurred in the weld joint, which are affected greatly by residual stresses. This ...
Effect of Impact Pressure on Reducing the Weld Residual Stress by Water Jet Peening in Repair Weld to 304 Stainless Steel Clad Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stainless steel clad plate manufactured by explosive bonding is widely used in the chemical industry, but cracks are often initiated in the clad layer. Repair welding is a popular method to repair the cracked zone. But ...
Effect of Temperature Fluctuation on Creep and Failure Probability for Planar Solid Oxide Fuel Cell
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The creep and failure probability of a planar solid oxide fuel cell (SOFC) through a duty cycle is calculated by finite element method (FEM) and Weibull method, respectively. Two sealing methods, namely, rigid seal and ...
Residual Stress Distribution in Hard Facing of Pressure Relief Valve Seat
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, for the hardfacing of springloaded pressure relief valve seats, the residual stress distributions after the tungsten inert gas welding, (TIG) postwelded heat treatment and subsequent surface turning were ...
Evaluation of Through-Thickness Residual Stresses by Neutron Diffraction and Finite-Element Method in Thick Weld Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Through-thickness distributions of the welding residual stresses were studied in the range of 50–100 mm thick plates by using finite-element modeling (FEM) and neutron diffraction measurements. In order to simulate the ...
Experimental and Numerical Study on the Reduction of Residual Stress in the Fillet Weld by Overlay Welding and Cutting Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fillet weld joint is widely used in engineering structures, but a lot of failures have been generated in the fillet joint affected greatly by weld residual stress, and it is very important to decrease the residual stress. ...

Neutron Diffraction Measurement and Numerical Simulation to Study the Effect of Repair Depth on Residual Stress in 316L Stainless Steel Repair Weld
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Welding is often used to repair the defects in pressure vessels and piping, but residual stresses are generated inevitably and have a great effect on structure integrity. According to the defect size, different repair depth ...
Determination of Repair Weld Residual Stress in a Tube to Tube-Sheet Joint by Neutron Diffraction and the Finite Element Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Repair welding is a popular method to repair the leakage zone in tube-to-tubesheet joint of shell-tube heat exchangers. But the repaired residual stresses are generated inevitably and have a great effect on stress corrosion ...
On Residual Stress and Relief for an Ultra-Thick Cylinder Weld Joint Based on Mixed Hardening Model: Numerical and Experimental Studies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Residual stress distributions as welded and after local postwelding heat treatment (PWHT) of butted weld joint of a huge cylinder with ultra-thick wall were investigated by finite element (FE) simulations and measurement. ...
