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.

Ultrasonic Evaluation at the Interface of Aluminum/Steel Obtained by TIG Welding
Qumrul Ahsan,Hiroshi Kato +1 more
TL;DR: In this paper, a thorough metallographic analyses using optical and scanning electron microscopy were carried out to observe Al-5%Si interface and ultrasonic measurements by immersion and scanning acoustic microscopy are made to characterise the bond at Al-Steel interface.
Journal Article
Effect of SMA Welding Electrodes on Mechanical and Corrosion of Low-Carbon Steel Joint
TL;DR: In this article, the effect of Shielded Metal Arc (SMA) welding electrodes on mechanical and corrosion of low carbon steel joint was investigated, and it was observed that improper choice of electrode type could affect the mechanical properties and corrosion rate of low-carbon steel joints.
Proceedings ArticleDOI
Data Analysis Tool and Image Acquisition System for Linear Arc Weld Deposition Evaluation
Bryan Stefan Galani Pernambuco,Cristiano Rafael Steffens,Adriano Velasque Werhli,Silvia Silva da Costa Botelho +3 more
TL;DR: An acquisition methodology for generating a weld image dataset, as well as a software tool that makes possible to analyze, process and visualize each frame from recorded linear welding, providing per sample statistics and a framework to draw annotations of the due video are presented.
Economic Analysis and Justification for Automated Welding Systems
TL;DR: In this article, a new welding process for a company in the Oil & Gas industry, ensuring method consistency and performance quality of their steel drill bit while increasing overall production is presented.
Journal ArticleDOI
Proper Heat Treatment to Reduce Intergranular Corrosion Susceptibility of Austenitic 304 and Ferritic 430 Stainless Steels
TL;DR: In this paper, a heat treatment at a temperature of 900°C for 36 hours followed by water quenching was used to prevent the formation of chromium carbides and promote the diffusion of the chromium back to replenish chromium-depleted zones.
