Journal ArticleDOI
Spatial variation of melt pool geometry, peak temperature and solidification parameters during laser assisted additive manufacturing process
TL;DR: In this article, a three-dimensional heat transfer and material flow model is developed to numerically simulate the temperature and velocity fields in a laser assisted layer by layer deposition process with coaxially fed powder particles.
Journal ArticleDOI
Modeling of heat transfer and fluid flow during gas tungsten arc spot welding of low carbon steel
TL;DR: In this article, the evolution of temperature and velocity fields during gas tungsten arc spot welding of AISI 1005 steel was studied using a transient numerical model and the calculated geometry of the weld fusion zone and heat affected zone and the weld thermal cycles were in good agreement with the corresponding experimental results.
Journal ArticleDOI
Problems and issues in laser-arc hybrid welding
TL;DR: Hybrid welding as mentioned in this paper combines the combination of a laser and an electrical arc to overcome problems commonly encountered during either laser or arc welding such as cracking, brittle phase formation and porosity.
Journal ArticleDOI
Metallurgy, mechanistic models and machine learning in metal printing
TL;DR: In this paper, the authors examined advances in metal printing focusing on metallurgy, as well as the use of mechanistic models and machine learning and the role they play in the expansion of the additive manufacturing of metals.
Journal ArticleDOI
Building digital twins of 3D printing machines
TL;DR: In this paper, the main building blocks of a first generation digital twin of additively manufactured (AM) components are presented from the viewpoints of researchers from several organizations, and a perspective of the current status and research needs are provided.
