TLDR
In this paper, the authors evaluated the use of activated flux TIG (ATIG) welding for the austenitic stainless steels with fluxes of only one major component and found that even the very simple flux that was used can greatly increase the penetration of the weld bead.About:

Development of an advanced A-TIG (AA-TIG) welding method by control of Marangoni convection
TL;DR: In this article, the effect of the concentration of O-2 and CO2 in the shielding gas on the weld shape was studied for the bead-on-plate TIG welding of SUS304 stainless under He-O2 and He-CO2 mixed shielding gases.

Marangoni convection and weld shape variation in A-TIG welding process
TL;DR: In this article, the flux effect on TIG weld shape variations is investigated by application of the heat transfer and fluid flow model, and the simulation makes use of Nimonic 263 alloy, TiO,TiO2 and Ti2O3 as the flux.

Weld Penetration and Marangoni Convection with Oxide Fluxes in GTA Welding
TL;DR: In this article, the authors investigated the effect of active flux on the Marangoni convection in the welding pool, and showed that the depth/width ratio of the weld pool was closely related to the oxygen content in the pool.

Factors affecting variable weld penetration
Kenneth C. Mills,B. J. Keene +1 more
TL;DR: In this article, it was concluded that the Heiple-Roper theory provides a satisfactory explanation for variable weld penetration, namely, the direction and the strength of the fluid flows in the weld pool caused by Marangoni convection are responsible for the large differences in weld penetrption observed with different casts.

Heat- and fluid-flow phenomena in weld pools
G. M. Oreper,Julian Szekely +1 more
TL;DR: In this paper, a mathematical formulation for the transient development of the fluid-flow field and the temperature field in a liquid pool, generated by a spatially variable heat flux falling on an initially solid metal block, is presented.

Activating flux - increasing the performance and productivity of the tig and plasma processes
TL;DR: In this article, the A-TIG process and its operating characteristics are presented and a mechanism is proposed by which the unique depth of weld pool penetration is achieved, and the performance in comparison to the conventional TIG plasma processes is highlighted and the potential areas of application are identified.
