Metal Transfer and Arc Plasma in Gas Metal Arc Welding
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 the influences of several competing forces including gravity, electromagnetic force, arc pressure, plasma shear stress, a...
متن کاملControl of pulsed gas metal arc welding
This paper presents a control system for manual pulsed Gas Metal Arc Welding (GMAW). This system consists of a current controller, which makes it possible to shape the current during welding, and two important components, which are the key issues discussed in this paper. These components include an arc length controller and a metal transfer controller. The arc length controller is based on a no...
متن کاملDynamic Behaxior of Gas Metal Arc Welding
Gas Metal arc Welding (GMABQ has become the most addely used process for joining of steel plates due to its high productixity, simplicity of equipment and ease of use. Although the process of melting of the electrode and development of the weld deposit has been studied for 40 years, the dynamic nature of the process has not been studied in detail because accurate models are computationally inte...
متن کاملNumerical Analysis of Metal Transfer in Gas Metal Arc Welding
METAL transfer describes the process of the molten metal movement from the electrode tip to the workpiece in gas metal arc welding (GMAW). A better understanding of the metal transfer process is important for improvements in the quality and productivity of welding. While several distinct modes of the metal transfer have been classified,[1] the globular and spray transfer modes have received att...
متن کاملEffects of shielding gas compositions on arc plasma and metal transfer in gas metal arc welding
This article presents the effects of shielding gas compositions on the transient transport phenomena, including the distributions of temperature, flow velocity, current density, and electromagnetic force in the arc and the metal, and arc pressure in gas metal arc welding of mild steel at a constant current input. The shielding gas considered includes pure argon, 75% Ar, 50% Ar, and 25% Ar with ...
