The Effect of Groove Shape on Molten Metal Flow Behaviour in Gas Metal Arc Welding [PDF]

open access: yesMaterials, 14(23), 7444 (2021), 2021
One of the challenges for development, qualification and optimisation of arc welding processes lies in characterising the complex melt-pool behaviour which exhibits highly non-linear responses to variations of process parameters. The present work presents a simulation-based approach to describe the melt-pool behaviour in root-pass gas metal arc welding

Quantitative Evaluation of SPH in TIG Spot Welding [PDF]

open access: yes, 2021
While the application of the Smoothed Particle Hydrodynamics (SPH) method for the modeling of welding processes has become increasingly popular in recent years, little is yet known about the quantitative predictive capability of this method. We propose a novel SPH model for the simulation of the tungsten inert gas (TIG) spot welding process and conduct
