High-frequency pulse-modulated square wave AC TIG welding of AA6061-T6 aluminum alloy
TL;DR: In this article, a bead-on-plate welding of 6-mm thick AA6061-T6 aluminum alloy is used to characterize the high-frequency pulse-modulated square wave AC TIG (HFPM AC-TIG) welding.
Journal ArticleDOI
Research status and future perspectives on ultrasonic arc welding technique
TL;DR: In this article, the authors summarized the effect mechanisms of ultrasonic on the arc characteristics and molten pool behaviors during arc welding, and briefly discussed the association mechanism for ultrasonic vibration and electromagnetic field.

Arc welding of zirconium and its alloys: A review
TL;DR: In this article, an overview of publications on arc welding of zirconium and its alloys for seven decades is provided, where the main attention is paid to the parameters of the gas tungsten arc, plasma arc, and gas metal arc welding methods.
Journal ArticleDOI
Control of gravity effects on weld porosity distribution during variable polarity plasma arc welding of aluminum alloys
TL;DR: In this paper, variable polarity plasma arc (VPPA) nonvertical-up welding produces pores in specific positions (on the upper side of the welded joint) rather than throughout the whole welded joints due to the effect of gravity.

Investigation into arc constriction by active fluxes for tungsten inert gas welding
D.S. Howse,W. Lucas +1 more
TL;DR: The most dominant mechanism for increased penetration is considered to be arc constriction rather than a change in the surface tension of the molten pool as mentioned in this paper, which is the most common mechanism used in tungsten inert gas welding.

Selection of parameters of pulsed current gas metal arc welding
P.K. Palani,N. Murugan +1 more
TL;DR: In this paper, a detailed study of the pulsed GMA welding, the effects of pulse parameters and different methodologies adopted for selecting these parameters to obtain better quality welds is presented.

Computer Simulation of Convection in Moving Arc Weld Pools
Sindo Kou,Y. H. Wang +1 more
TL;DR: In this paper, a computer simulation for three-dimensional convection in moving arc weld pools was described, with three distinct driving forces for flow considered, i.e., the electromagnetic force, the buoyancy force, and the surface tension gradient on the pool surface.
Journal ArticleDOI
Arc characteristics and behaviour of metal transfer in pulsed current GMA welding of aluminium alloy
TL;DR: In this article, the effect of pulse parameters has been studied by considering their hypothetically proposed summarised influence defined by a dimensionless factor ϕ ǫ = [( I b / I p ) ft b ], mean current and arc voltage.
