Using double ellipsoid heat source model for prediction of HAZ grain growth in GTAW of stainless steel 304

TL;DR: In this article , a finite element simulation of heat transfer in GTAW of stainless steel 304 is investigated using double ellipsoid heat source model, and the simulation results are compared with the results obtained from the analytical Rosenthal model and also experimental data.
Journal ArticleDOI

Microstructure characteristics and liquation behavior of fiber laser welded joints of Mg-5Zn-1Mn-0.6Sn alloy sheets

TL;DR: In this paper, the appearance and microstructures of the welding joints and liquation behaviors in the partially melted zone (PMZ) were investigated, and the results showed that, with a lower welding power and higher welding speed, the width and depth of the joints decrease.

Improved design bases of welded joints in seawater

TL;DR: In this article, the authors investigated and established a precise, thorough and detailed database from series of experimental testing of submerged arc welded, SAW, specimens of various thicknesses typically applied in offshore structures and foundations.

Tensile and fracture behavior of pulsed gas metal arc-welded Al-Cu-Li

TL;DR: In this paper, the effect of pulse frequency on microstructure, microhardness, tensile strength, and crack growth resistance as well as fracture path were studied, and it was observed that the mechanical properties of the joints made with GMAW-P were comparable to the laser welded joints.

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

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.
