Understanding fume formation by GMAW
1999The control of exposure to welding fume is necessary to meet health and safety obligations. The work reported here is a continuation of a successful Cooperative Research Centre project, that has revealed how two different mechanisms are responsible for generation of fume in Gas Metal Arc Welding (GMAW).

Influence of Preheated Wire on GMAW Process
Advanced Materials Research, 2013An hot-wire GMAW process is proposed in which the wire is preheated by a TIG arc to enhance the wire melting, and the process is aimed at high efficiency welding with a low level heat input. The welding system is designed, the wire temperature is monitored and the metal transfer and arc behavior is observed.

Optimization procedures for GMAW of bimetal pipes
Journal of Materials Processing Technology, 2011Abstract Autogenous gas tungsten arc welding (GTAW) and pulse rapid arc gas metal arc welding (GMAW) of butting bimetal (Bubi) pipelines were studied. GMAW was carried out from the outside of the pipe while GTAW was done from the inside to prevent lack of penetration and to promote a smooth internal weld bead surface.

Pendant droplet oscillation during GMAW
Science and Technology of Welding and Joining, 2006This paper deals with pendant droplet oscillation in pulsed current gas metal arc welding (GMAW). Using a constant current power source, bead on plate welds were made on mild steel plates. The frequency of the pendant droplet oscillation was monitored visually (using a high speed video camera) and electronically (by analysis of the voltage signals ...

An Evaluation System of Pulsed GMAW Process
Applied Mechanics and Materials, 2013A process evaluation system for pulsed gas metal arc welding (GMAW-P) based on the LabVIEW platform has been developed. This system is comprised of two modules, a simultaneous display module and a data analysis module. Using these modules, the system can not only provide a comprehensive direct viewing display of the welding electric signal and high ...

Control of penetration zone GMAW
2016Thermal properties of the base metal, shielding medium and the nature of the electrode metal transfer to a great extent determine the penetration area formation in gas-arc welding. It is not always possible to take into account the influence of these factors on penetration front forming within the existing models.

Multiple-Wire Welding GMAW and SAW
2019This chapter presents the developments in multiple-wire welding from the technology and research perspectives. The multiple-wire welding uses more than one electrode, in which the electrodes travel simultaneously with the same or different feed rates through a joint contact tube.
