Predicting of bead undercut defects in high-speed gas metal arc welding (GMAW)

Frontiers of Materials Science in China, 2008
In the gas metal arc welding (GMAW) process, when the welding speed reaches a certain threshold, there will be an onset of weld bead undercut defects which limit the further increase of the welding speed. Establishing a mathematical model for high-speedGMAWto predict the tendency of bead undercuts is of great significance to prevent such defects. Under

Analysis of jig application to inhibit welding deformation on SUS304 steel plates for gas metal arc welding (GMAW)

2017 International Conference on Applied System Innovation (ICASI), 2017
This research uses the finite element analysis software MSC.MARC to analyze the welding deformation, as well as the residual stress, of 6 mm thick stainless steel plates, type SUS304. The discussion includes the usefulness of applying jigs during the welding process and how this impacts the resulting welded structure, when pressure is applied.

Modeling and Optimization of Gas Metal Arc Welding (GMAW) Process

2012
Weld quality is greatly affected by the operating process parameters in the gas metal arc welding (GMAW) process. The quality of the welded material can be evaluated by many characteristics, such as bead geometric parameters, deposition efficiency, weld strength, weld distortion, et cetera.

Effect of Bevel Angle and Welding Current on T-Joint Using Gas Metal Arc Welding (GMAW)

2018
In this study, the effects of various welding parameters on welding strength in mild steel A36, welded by gas metal arc welding with fillet joint under 1F position were investigated. The welding current and the angle of bevel are the variable parameters, while welding speed was chosen as constant parameter.

Effect of Shielding Gas Mixture on Gas Metal Arc Welding (GMAW) of Low Carbon Steel (LR Grade A)

Key Engineering Materials, 2016
The aimed of this research is to determine the feasibility and effect of the mixture of the shielding gas in the physical and mechanical properties. Low carbon steel LR grade A in a thickness 12 mm were joined in butt joint types using GMAW (Gas Metal Arc Welding) with groove’s gap 5 mm and groove angle’s 400 with variation of shielding gas composition.

Estimation and control of droplet size and frequency in projected spray mode of a gas metal arc welding (GMAW) process

ISA Transactions, 2011
New estimators are designed based on the modified force balance model to estimate the detaching droplet size, detached droplet size, and mean value of droplet detachment frequency in a gas metal arc welding process. The proper droplet size for the process to be in the projected spray transfer mode is determined based on the modified force balance model

Neutron diffraction residual stress measurements of welds made with pulsed tandem gas metal arc welding (PT-GMAW)

Powder Diffraction, 2014
Pulsed tandem gas metal arc welding (PT-GMAW) is being developed to increase productivity and minimise weld-induced distortion in ship-building. The PT-GMAW process was used in pulse–pulse mode to butt-weld two different strength and thickness steels; the residual stress and hardness profiles of the welds are reported and correlated.

Erratum to: Mechanisms of weld pool flow and slag formation location in cold metal transfer (CMT) gas metal arc welding (GMAW)

Welding in the World, 2017
This work investigates the weld pool flow behavior by observing the flow pattern of floating slag particles for cold metal transfer (CMT) gas metal arc welding (GMAW) using three different welding wires. These wires contain different amount of deoxidizers in the form of silicon and manganese.
