Liquation cracking in partial-penetration aluminum welds: Effect of penetration oscillation and backfilling
TL;DR: In this article, a gas metal arc welding (GMAW) with Ar shielding was conducted on binary Al-Cu Alloy 2219 with various filler metals, including 1100, 2319, 4145, 4047, and 2319 plus extra Cu.

Influence of Welding Parameters on Microstructure and Mechanical Performance of Resistance Spot Welded High Strength Steels
Hadi Ghazanfari,Malek Naderi +1 more
TL;DR: Hardness and microstructural examinations were carried out in order to examine the influence of welding parameters on the welded joints as discussed by the authors, which revealed that hardness mapping technique provides one of the best methods for the physical and mechanical understanding of heterogeneous microstructures using hardness criterion.

Analytical thermal model of conduction mode double sided arc welding
Y. Kwon,D. C. Weckman +1 more
TL;DR: An analytical thermal model of conduction mode double sided arc welding (DSAW) was derived and used to predict the weld pool dimensions and shapes and temperatures within 2?5 and 1?15 mm thick AA5182 Al alloy sheets as functions of the primary DSAW parameters as discussed by the authors.

A study on transverse weld cracks in thick steel plate with the FCAW process
H. W. Lee,S. W. Kang,D. S. Um +2 more
TL;DR: In this paper, the transverse crack in thick plate welding is discussed with respect to deposited metal, which is caused by the complex interaction of the diffusible hydrogen supply, tensile residual stress and susceptible microstructure.

A review on selective laser sintering/melting (SLS/SLM) of aluminium alloy powders: Processing, microstructure, and properties
TL;DR: In this article, the state of the art in selective laser sintering/melting (SLS/SLM) processing of aluminium powders is reviewed from different perspectives, including powder metallurgy (P/M), pulsed electric current (PECS), and laser welding of aluminium alloys.
Journal ArticleDOI
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.
Journal ArticleDOI
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.
