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.
Abstract: This paper presents details of the A-TIG process and its operating characteristics. A mechanism is proposed by which the unique depth of weld pool penetration is achieved. Whilst there are undoubted significant productivity benefits to be gained, its performance in comparison to the conventional TIG plasma processes is highlighted and the potential areas of application are identified.

TL;DR: In this article, the effect of specific oxide fluxes on the surface appearance, weld morphology, retained δ ferrite content, hot cracking susceptibility, angular distortion and mechanical properties obtained with the tungsten inert gas (TIG) process applied to the welding of 5 mm thick austenitic stainless steel plates.
Abstract: The aim of the present study was to investigate the effect of specific oxide fluxes on the surface appearance, weld morphology, retained δ ferrite content, hot cracking susceptibility, angular distortion and mechanical properties obtained with the tungsten inert gas (TIG) process applied to the welding of 5 mm thick austenitic stainless steel plates. An autogenous gas tungsten arc welding process was applied to stainless steels through a thin layer of activating flux to produce a bead on plate welded joint. The MnO2 and ZnO fluxes used were packed in powdered form. The experimental results indicated that the 80% MnO2–20% ZnO mixture can give full penetration and also a satisfactory surface appearance for type 304 stainless steel TIG flux welds. TIG welding with MnO2 and/or ZnO can increase the measured ferrite number in welds, and tends to reduce hot cracking susceptibility in as welded structures. It was also found that TIG flux welding can significantly reduce the angular distortion of stainless...
