Summary: This study investigated the weld residual stresses in a mock-up of a nuclear safe-end dissimilar metal weld (DMW) joint using neutron diffraction, the contour method, and finite element (FE) modelling. The results showed high levels of tensile residual stresses in the hoop direction of the weld joint, with reasonable consistency between the experimental and numerical results.

Summary: The welding-induced residual stresses in dissimilar metal butt-welded joints between P92 steel and SUS304 stainless steel were investigated using finite element analyses and experimental measurements. Factors such as solid-state phase transformation, strain hardening, annealing effect, and thermal expansion coefficient differences were found to have significant influence on the formation of longitudinal residual stresses. The butt-welded joint with X-groove was suggested to be superior in reducing high tensile residual stress compared to the joint with single V-groove.

Summary: Dissimilar metal weld overlays are commonly used to reinforce stainless steel pipe welds in BWR reactors, and have been applied for repair purposes as well. The use of weld overlays can change residual stresses from tensile to compressive, providing structural reinforcement. Computational analysis showed that increasing the overlay length significantly increased compressive residual stresses in the dissimilar metal weld.

Summary: This study proposes a novel method for evaluating uniform residual stresses in cylindrical bodies by simulating different residual stress states in cylindrical bodies and using the method described in ASTM E837 standard for evaluation. The four sets of calibration coefficients in the new procedure show a negligible relative error in evaluating residual stresses.

Summary: This study investigates the effects of CO2 rapid cooling technique on reducing residual stress in both similar and dissimilar metals welds. A thermo-mechanical numerical model is developed and validated with experimental data to analyze the effectiveness of various CO2 rapid cooling parameters. The results show that smaller CO2 nozzle can lead to significantly lower residual stress magnitude, but uniformity in residual stress distribution may not always be achieved, especially in dissimilar metals welds. Recommendations are provided for minimizing residual stress in welded parts based on the findings.

Summary: This study presents three calibration approaches for the hole-drilling method (HDM), using a total of 72 finite element models and 144 simulations to calibrate the strain sensors' measurements. The results show better estimation of residual stresses (RSs) using the third approach, while the second approach underestimates the stresses.

Summary: This study investigates the application of directly deposited thin film strain gauges in the incremental hole drilling method. The results show that the residual stress depth profiles obtained from the directly deposited strain gauges match those obtained from conventional polymer foil-based strain gauges. The advantages of direct deposition include simplified zero depth setting and the ability to create various rosette designs for evaluating the strain field.

Summary: This study investigated the influence of different strain release coefficient calibration methods on the measurement results of welding residual stress, finding that high-value WRSs are significantly overestimated when calibrated using the formula method and experiment. Consideration of stress biaxiality revealed specific distribution trends of WRSs on an orthotropic steel deck.

Summary: In the welding process of high-strength steel, the formation of welding residual stress (WRS) due to intense temperature change affects the fatigue crack growth rate. Developing an accurate finite element (FE) model that considers solid-state phase transformation (SSPT) and material hardening law is crucial for predicting the WRS distribution and improving the quality of welded structures. Experimental tests and numerical simulations were conducted on EQ56 HSS, and the results showed that plastic hardening laws and the inclusion of SSPT behavior in the FE model significantly influenced the precision of the predicted WRS distribution.

Summary: This study investigates the welding-induced residual stresses and distortions of butt-welded non-corroded and corroded steel plates, taking into account environmental conditions and material properties. The importance of considering steel ageing in the repair process is highlighted, and the developed methodology allows for critical operational decisions to be made with greater ease and confidence. Different welding sequence scenarios can also be analysed to minimize repair costs in repairing ageing structures.

Summary: This study investigates the effects of the matrix material constitutive model and the presence of defects on the development of manufacturing induced residual stresses using Finite Element (FE) analysis. The results suggest that viscoelastic matrix properties should be considered in order to accurately reproduce the residual stress fields, and the possible presence of cracks at the tow/matrix interface should not be neglected.
