Gas tungsten arc welding
Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A const...

متن کاملMetal 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...
