Welding is a major manufacturing process that joins two or more pieces of materials together
through heating/mixing them followed by cooling/solidification. The goal of welding …

Self-equilibrating residual stresses may occur in materials in the absence of external loading
due to internal strain inhomogeneity. While favourable distributions of residual stress can …

In this study a novel micro-rolling set-up was installed on a directed energy deposition
additive manufacturing system to achieve in-situ grain refinement and porosity closure. A …

Thin-walled pipes have been widely used in chemical facilities and propulsion structures,
where the distortion problem induced by welding fabrication is common and prominent …

Thin plates are widely used in aerospace, naval, and automobile industries to reduce the
weight of component. Welding distortion occurring in thin plate joint or structure is inevitable …

A local solid model and a global shell model were employed for fast prediction of
deformation in laser welded thin sheets based on inherent strain theory. Transient thermo …

Abstract In a Thermal-Elastic-Plastic (TEP) FE analysis to investigate welding induced
buckling of large thin plate welded structure such as ship panel, it will be extremely difficult …

Welding induced buckling in thin plate structures significantly affects productivity and
fabrication cost due to post-weld correction works. Transient thermal tensioning (TTT) as an …

Due to the increasing use of thin plates in lightweight welded structure, welding induced
buckling may occur in such thin plate welded structure. In this study, welding induced …

The mechanisms of post-weld rolling and how it reduces and eliminates residual stress and
distortion are poorly understood. Finite element analysis was applied to two different …
