Feasibility of narrow gap welding using the cold-wire gas metal arc welding (CW-GMAW) process
Welding in the World, Le Soudage Dans Le Monde, 2017This article evaluates the performance of the cold-wire gas metal arc welding (CW-GMAW) process for narrow gap girth welding. The CW-GMAW process is characterized by the introduction of a continuously fed non-energized wire (cold-wire) into the electric arc/weld pool region.

Biological Trace Element Research
Welding activities are known to expose workers to metal fumes, but few studies have focused on assessing the internal exposure of apprentices in learning environments. This study aimed at determining internal doses of metals in apprentices performing gas metal arc welding (GMAW) during their training course.

Microstructural analysis of the anode in gas metal arc welding (GMAW)
Journal of Materials Processing Technology, 2009Abstract The nature of the applied shielding gas has a strong influence on arc stability and transfer metal mode of the welding process. In particular, increase of the percentage of carbon dioxide in argon induces the increase of the transition current value from the globular to spray metal transfer mode. This work shows that these effects are linked

Heat input in full penetration welds in gas metal arc welding (GMAW)
The International Journal of Advanced Manufacturing Technology, 2013Weld bead characteristics are metallurgically controlled by heat input, which depends on the welding parameters. However, for numerous welding specialists, an accurate measurement of the current, voltage, and welding speed is enough for preventing unambiguous process specifications. But a comprehensive knowledge of the effect of others parameters, such

Improving the dynamic metal transfer model of gas metal arc welding (GMAW) process
The International Journal of Advanced Manufacturing Technology, 2014This work presents an improved model of characteristic equations for gas metal arc welding process. In this paper, a dynamic electrical model is introduced as a rectifier power source instead of pervious common simple models. In addition, an electrical resistance model is proposed for bridge in short circuit period to consider the effect of melting ...

Parameters optimization using factorial analysis method for Gas Metal Arc Welding (GMAW) process
AIP Conference Proceedings, 2021Gas Metal Arc Welding (GMAW) is the most widely used process and an essential component in many industrial operations. GMAW welding parameters are the most significant factors influencing the quality, productivity, and cost of the welding joint. Therefore, there is a need to optimize the GMAW process to achieve welding quality because currently, the ...

Application of a Front Tracking Method in Gas Metal Arc Welding (GMAW) Simulation
Journal of Manufacturing Science and Engineering, 2004A numerical model is developed to simulate the short-circuiting metal transfer process during gas metal arc welding (GMAW). The energy equation and the Marangoni convection are considered for the first time in analyzing the short-circuiting time. A front-tracking free surface method explicity tracks the profile of the liquid bridge. The electromagnetic
