International Journal of Heat and Mass Transfer, 2020
Abstract Based on the VOF method, a three-dimensional numerical analysis model coupling both droplets and arc behaviors is developed to simulate the metal transfer and arc plasma flow processes in underwater wet flux-cored arc welding. The relationships between several physical quantities such as droplet shape and temperature, electromagnetic force ...

Spectroscopic analysis of the arc plasma of underwater wet flux-cored arc welding
Journal of Materials Processing Technology, 2013Abstract Experiments in air and under water (0.4 m depth) were conducted and the spectrum signals collected. The width of the weld under water was about two-thirds of the width in air, suggesting that the arc plasma was compressed by the water environment. The two sets of spectrum signals were largely similar except for the ultraviolet spectrum, from

Numerical simulation of bubble and arc dynamics during underwater wet flux-cored arc welding
Journal of Manufacturing Processes, 2020Abstract The dynamic behaviors of underwater bubbles and arcs are critical to welding processes and weld quality in underwater wet flux-cored arc welding. In this study, bubble evolution promoted by an arc plasma and flux decomposition was simulated using hydrodynamic equations.

Arc Characteristic and Metal Transfer of Pulse Current Horizontal Flux-Cored Arc Welding
Transactions of Tianjin University, 2017In this work, we utilized high-speed video photography to investigate the arc characteristics, metal transfer behavior, and welding spatter of the pulse-current flux-cored arc welding (P-FCAW) process in the horizontal position. The results indicate the presence of a stable “flux pole” during both the pulse-on and pulse-off periods when the mean ...
