Journal ArticleDOI
Friction stir welding of mild steel: Tool durability and steel microstructure
TL;DR: In this article, a three-dimensional heat and mass flow model was used to assess tool durability and define the domains of satisfactory tool life in the context of welding difficult aluminium alloys.
Journal ArticleDOI
Physics-informed machine learning and mechanistic modeling of additive manufacturing to reduce defects
TL;DR: In this paper, a combination of physics-informed machine learning, mechanistic modeling, and experimental data is used to reduce the occurrence of common defects in additive manufacturing, such as balling, cracking, lack of fusion, porosity, and surface roughness.
Journal ArticleDOI
Optimization of the johnson-mehl-avarami equation parameters for α-ferrite to γ-austenite transformation in steel welds using a genetic algorithm
TL;DR: In this article, a nonisothermal Johnson-Mehl-Avarami (JMA) equation with optimized JMA parameters is proposed to represent the kinetics of transformation of α-ferrite to γ-austenite during heating of 1005 steel.
Journal ArticleDOI
Tailoring gas tungsten arc weld geometry using a genetic algorithm and a neural network trained with convective heat flow calculations
S. Mishra,Tarasankar Debroy +1 more
TL;DR: In this article, a real number based genetic algorithm and a neural network are used to determine a population of solutions by minimizing an objective function that represents the difference between the calculated and the desired values of weld pool penetration and width.
Journal ArticleDOI
Pore formation during continuous wave Nd:YAG laser welding of aluminium for automotive applications
TL;DR: In this article, the influence of laser beam defocus on pore formation during continuous wave laser welding of automotive aluminium alloys is investigated, which is an important concern in laser welding.
