Analysis of arc pressure effect on metal transfer in gas-metal arc welding [PDF]

open access: greenJournal of Applied Physics, 1991
Metal transfer has been analyzed using both the static force balance method and the pinch instability theory. The influences of arc pressure as well as electromagnetic pressure in the development of instability in the cylindrical molten metal were considered.

Analysis of metal transfer in gas metal arc welding [PDF]

open access: yesAIP Conference Proceedings, 2019
The objective of this research is to find the parameters in gas metal arc welding for the application of steel. The force and velocity with which the droplet falls in the weld pool during the welding process were analysed. The effects of different shielding gases used in the welding process were studied by varying the percentage of different shielding ...
