In this study, the weld residual stresses (RS) in a 25 mm thick ferrite steel plate with newly
developed low-temperature transformation (LTT) welding wire were investigated by finite …

The microstructure development and mechanical behaviour of dissimilar metal welds
between ferritic and austenitic steel, as well as their application in nuclear power plants, are …

Numerical finite element analyses were combined with experimental observation of a single-
pass autogenous beam weld in SA508 Gr. 3 Cl. 1 ferritic steel. Two weldment sets were …

The nuclear reactor pressure vessel (RPV) is the most critical pressure boundary and safety
structure in a nuclear power plant, as it contains the reactor core and coolant. RPVs, which …

Microstructural evolution of the heat-affected zone (HAZ) seriously affects the mechanical
properties of the welded joints. In this paper, QP980 steels were butt-welded by fiber laser …

Austenitic stainless steel microstructures produced by directed energy deposition (DED) are
analogous to those developed during welding, particularly high energy density welding. To …

The residual stress distribution of duplex stainless steel multi-pass weld joint and its
formation mechanism still lacks systematic research. In this study, neutron diffraction and …

Dilution represents the contribution from base material to weld metal and its important effects
are complicated for multi-pass steel welds. In this study, the dilution was determined for each …

Dissimilar joints of DP600-DP980 were made by fiber laser welding with a focused and
defocused beam. The defocused laser intensified the hardness drop of the softened heat …

Safety-critical pressure vessels in pressurised water reactors (PWRs), such as the reactor
pressure vessel and the steam generators, have been fabricated using arc welding …
