... to the enlarged action area of the hybrid heat sources. Since the underlying mechanisms investigated could also occur in other high-energy beam processes, such as hybrid laser-arc welding, the results of this study will give some insight into the practical applications. There are complicated mechanisms existing...

... Relevant to Welding Metallurgy,” Metall. Trans. B, 19B, pp. 483–491) and was finally used for calculating fluid flow and heat transfer in gas tungsten arc welding of a super duplex stainless steel, SAF 2507. In this study, the authors applied the multicomponent surfactant mass transfer model to investigate...

...J. Hu; H. L. Tsai This article analyzes the transient complex heat transfer and fluid flow in molten metal and arc plasma during the gas metal arc welding process. The model predicts the formation, growth, detachment, and transfer of droplets from the tip of a continuously fed electrode under...

...Nilanjan Chakraborty; Suman Chakraborty The effects of positive and negative surface tension coefficients ( ∂ σ sur ∕ ∂ T ) on both laminar and turbulent weld pool convection are numerically studied for a typical gas tungsten arc welding (GTAW) process. Three-dimensional turbulent weld pool...
