Study of the arc voltage in gas metal arc welding [PDF]
Journal of Physics D: Applied Physics, 2018 In this paper, the voltage drop in pulsed gas metal arc welding (GMAW) is studied, focussing on the contributions of the different sections of wire and arc along the current path and their dependence on arc length and current. A typical pulsed GMAW process of mild steel in the one drop per pulse modus is considered as a reference.

Advanced gas metal arc welding processes [PDF]
The International Journal of Advanced Manufacturing Technology, 2012 There is an increased requirement in the automotive, food and medical equipment industries to weld heat-sensitive materials, such as thin sheets, coated thin plates, stainless steel, aluminium and mixed joints. Nevertheless, relevant innovations in arc welding are not widely known and seldom used to their maximum potential. In the area of gas metal arc

Metal Transfer and Arc Plasma in Gas Metal Arc Welding
Journal of Heat Transfer, 2006This 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 ...

Advancements in pulse gas metal arc welding
Journal of Materials Processing Technology, 2005Environmental concerns have driven manufactures to look for alternative materials like aluminium that are lighter in weight and possess good thermal and electrical conductivity. However, fabrication of alternative materials presents a considerable challenge for fabrication in volume production.

Control of pulsed gas metal arc welding
International Journal of Modelling, Identification and Control, 2006This 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.

Multifractal analysis for gas metal arc welding
The International Journal of Advanced Manufacturing Technology, 2017The gas metal arc welding (GMAW) is a complicated chaotic dynamic process and its arc electrical signals have the characteristics of both chaos and fractals. The multifractal can accurately depict the geometric characteristics and local scale behaviors of time series signals.
