Metal additive manufacturing (AM) is capable of producing complex parts, using a wide
range of functional metals that are otherwise very difficult to make and involve multiple …

Welding deformation and residual stress have negative influence on assembly accuracy and
service performance. Thermal elastic plastic (TEP) and inherent strain finite element …

In-process deformation methods such as rolling can be used to refine the large columnar
grains that form when wire+ arc additively manufacturing (WAAM) titanium alloys. Due to the …

The aluminium alloy wire 2319 is commonly used for Wire+ Arc Additive Manufacturing
(WAAM). It is oversaturated with copper, like other alloys of the precipitation hardening 2### …

Hybrid process of wire arc additive manufacturing (WAAM) and high-pressure rolling can
build large-scale components with low detrimental residual stress (RS) and distortion. We …

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 …

Post-build rolling can mitigate residual stress (RS) and distortion in large-scale components
built by wire arc additive manufacturing (WAAM). In this study, based on numerical …

Cold rolling can be used in-process or post-process to improve microstructure, mechanical
properties and residual stress in directed-energy-deposition techniques, such as the high …

Fusion welding causes joint deterioration when joining aluminum alloys, which limits the use
of aluminum alloy components in high-end equipment. This paper focuses on an overview of …

The orthotropic steel deck (OSD) is susceptible to fatigue damage under repeated traffic
loads, and the welding residual stress (WRS) is an important factor contributing to fatigue …
