Reviewing the Influence of Welding Setup on FE-Simulated Welding Residual Stresses
TL;DR: In this paper, the influence of microstructural changes in aluminum welds on the welding residual stresses has been investigated using finite element (FE) simulation techniques and the results are analyzed so that concrete suggestions regarding the investigated factors, acting as guidance to the practitioner can be presented.

Effect of welding sequence on residual stress distributions in GTA welding of AA5251 plate
TL;DR: In this paper, a thermo-mechanical model has been used to predict the temperature history and residual stress distribution in gas tungsten arc welding of AA5251 plates.
Dissertation
Coupled Field Modeling of Gas Tungsten Arc Welding
TL;DR: In this article, a 3D model for the thermo-mechanical analysis of thin stainless steel butt-joint plates has been developed, which incorporates the effects of thermal energy redistribution through weld pool dynamics into the structural behavior calculations.

Dislocation network in additive manufactured steel breaks strength–ductility trade-off
Leifeng Liu,Qingqing Ding,Yuan Zhong,Ji Zou,Jing Wu,Yu-Lung Chiu,Jixue Li,Ze Zhang,Qian Yu,Zhijian Shen +9 more
TL;DR: In this article, the authors show that the pre-existing dislocation network, which maintains its configuration during the entire plastic deformation, is an ideal modulator that is able to slow down but not entirely block the dislocation motion.
Journal ArticleDOI
Critical review of automotive steels spot welding: process, structure and properties
TL;DR: In this article, the fundamental understanding of structure-properties relationship in automotive steels resistance spot welds is discussed. And a brief review of friction stir spot welding, as an alternative to RSW, is also included.
Journal ArticleDOI
Revisiting fundamental welding concepts to improve additive manufacturing: From theory to practice
TL;DR: In this article, a unified equation to compute the energy density is proposed to compare works performed with distinct equipment and experimental conditions, covering the major process parameters: power, travel speed, heat source dimension, hatch distance, deposited layer thickness and material grain size.

Using deep neural network with small dataset to predict material defects
TL;DR: This study attempted to predict solidification defects by DNN regression with a small dataset that contains 487 data points and found that a pre-trained and fine-tuned DNN shows better generalization performance over shallow neural network, support vector machine, and DNN trained by conventional methods.
