Tungsten Inert Gas Welding and Design
2021TIG welding is an arc welding process that uses a non-consumable tungsten electrode for the weld and is adopted in some industries as a replacement of gas and manual metal arc welding. This is attributed to the fact that it uses inert gas shield to protect the weld pool. They are specifically preferred for joining magnesium and aluminum.

Weld Joint of Tantalum Sheet by Tungsten Inert Gas Welding
Materials Science Forum, 2021The 0.6 mm tantalum sheet was welded under argon atmosphere by Tungsten Inert Gas Welding (TIG) in order to obtain a welded joint with high-quality and high-reliability. Metalloscope, scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) were applied to analyze the joint.

Thorium exposure during tungsten inert gas welding with thoriated tungsten electrodes
Radiation Protection Dosimetry, 2003The exposure to 232Th from TIG welding with thoriated electrodes has been determined at five different workshops. Welding with both alternating and direct current was investigated. The exposure levels of 232Th were generally below 10 mBq m(-3) in the breathing zone of the welders.

Extracting weld penetration information in tungsten—inert gas welding
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2002Weld pool images provide abundant information about weld penetration while the weld penetration has a close relationship with the back weld width. The key to achieving weld penetration control is to establish a model describing the relationship between the front-side geometrical parameters of the weld pool and the back weld width with sufficient ...

Activating flux tungsten inert gas welding for enhanced weld penetration
Journal of Manufacturing Processes, 2016Abstract The flux assisted GTAW or A-TIG process developed at the Paton Welding Institute in 1960. Despite capable of offering a penetration up to 5–6 mm in a single pass weld, it could not find enough space in industrial applications, primarily due to few inherent unfavorable features: (a) two-step nature of the process, (b) poor weld-bead and (c ...

Surface Review and Letters, 2015
Surface contamination usually occurs during welding processing and it affects the welds quality largely. However, the formation of such contaminants has seldom been studied. Effort was made to study the contaminants caused by metal inert gas (MIG) welding and tungsten inert gas (TIG) welding processes of aluminum alloy, respectively.

Joining titanium materials with tungsten inert gas welding, laser welding, and infrared brazing
The Journal of Prosthetic Dentistry, 1995Titanium has a number of desirable properties for dental applications that include low density, excellent biocompatibility, and corrosion resistance. However, joining titanium is one of the practical problems with the use of titanium prostheses. Dissolved oxygen and hydrogen may cause severe embrittlement in titanium materials.
