چکیده
A compound external magnetic field (EMF) can be used to prevent weld bead defects by controlling the metal transfer and arc behaviors during high-speed gas welding. unified model containing filler metal, arc, pool, EMF was established study effect of on welding process. The heat mass among pool under action numerically analyzed. simulation results showed that high-temperature region in molten reduced temperature distribution more uniform after introduced. speed forward liquid flow front increased due inclination plasma, a small bulge formed at leading edge pool. Because periodic swing droplet, transverse filling strengthened. generated additional electromagnetic force inside analyzed, it had limited impact behavior.

Mechanically assisted droplet transfer process in gas metal arc welding
Gas metal arc welding has been generally accepted as the preferred joining technique due to its advantages in high production and automated welding applications. Separate control of arc energy and arc force is an essential way to improve the welding quality and to obtain the projected metal transfer mode. One of the most eVective methods for obtaining separate control is to exert an additional ...
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...

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 کاملThe influence of the arc plasma on the weld pool in simulations of arc welding
Results from a computational model of arc welding, in which the arc plasma, workpiece and electrode are treated self-consistently, are presented. It is demonstrated through three examples (the effect of shielding gas composition, metal vapour and electrode shape on the weld pool) that reliable prediction of weld pool depth and geometry requires that the arc plasma is included in the computation...
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...
