Multiphysics modelling of Gas Tungsten Arc Welding on ultra-thin-walled titanium tubing [PDF]

open access: yesarXiv, 2022
This thesis presents a novel multiphysics solver, named gtawFoam, for Gas Tungsten Arc Welding (GTAW) that is applied to simulate orbital GTAW on ultra-thin-walled titanium tubing. In this thesis, ultra-thin-walled tubing refers to tubing where the wall thicknesses are less than 500 $\mu m$.

Computational methods for creation materials with required composition and structure [PDF]

open access: yeschapter 17, pp. 445-464 in Materials Science book edited by Itzhak Mastai, Intech publ (2013), 2018
One of the most important and complicated problems in modern industry is to obtaining materials with the required chemical composition, structure and mechanical and physical properties. Solving this problem involves great deal of time and expense, and the results obtained might be far from the optimal solution.

Towards a Deep Learning-based Online Quality Prediction System for Welding Processes [PDF]

open access: yesarXiv, 2023
The digitization of manufacturing processes enables promising applications for machine learning-assisted quality assurance. A widely used manufacturing process that can strongly benefit from data-driven solutions is gas metal arc welding (GMAW). The welding process is characterized by complex cause-effect relationships between material properties ...
