A-TIG (activated flux tungsten inert gas) welding: – A review
Materials Today: Proceedings, 2021Abstract TIG welding faces low weld penetration as the major challenge which ultimately limits the productivity of the process. To mitigate this challenge and utilize the peerless benefits of TIG welding, a technique known as Activated flux tungsten inert gas (A-TIG) welding has been developed and is being widely researched upon.

Development of high frequency tungsten inert gas welding method
Materials & Design (1980-2015), 2013Abstract A new welding method, called high frequency tungsten inert gas (TIG) welding, was developed to decrease blowholes in a weld. A1050 aluminum alloy plates (100 mm l × 50 mm w × 5 mm t ) were welded at a frequency from 10 to 40 kHz. An Ar-1% hydrogen mixture was used as the shielding gas to generate blowholes in the experiments.

Fuzzy pattern recognition of tungsten inert gas weld quality
The International Journal of Advanced Manufacturing Technology, 1997In this paper, a fuzzy pattern recognition technique is applied to classifying aluminium weld quality in tungsten inert gas (TIG) welding. The pattern vector includes three components, that is, the front height, the back height, and the front width of weld.

A novel molten wire tungsten inert gas welding process
Science and Technology of Welding and Joining, 2019A novel molten wire tungsten inert gas welding process was presented. In this process, a welding arc is used to melt the workpiece, and a melting arc is used to melt the feeding wire. Metal transfer is separated from the melting of the wire and the workpiece, and the arcs are stable no matter the droplet transfer mode is spraying or globular.

Laser guided double tungsten inert gas welding of aluminium
ICALEO 2012: 31st International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2012TIG welding is a common, industrially established process. Its main advantage is the weld quality. The drawback is lower process speeds which can lead to heat affects, irreversibly destroyed material properties and work piece distortion. To overcome these process limits, two common TIG processes were combined with low power laser radiation. This double

Plasma–weld pool interaction in tungsten inert-gas configuration
Journal of Physics D: Applied Physics, 2013A three-dimensional (3D) transient model of a transferred argon arc in interaction with an anode material is presented and the results discussed. The model based on a finite volume method is developed using the open software @Saturne distributed by Electricite de France. The 3D model includes the characterization of the plasma gas and of the work piece

Flux bounded tungsten inert gas welding for enhanced weld performance—A review
Journal of Manufacturing Processes, 2017Abstract Flux Bounded Tungsten Inert Gas welding (FBTIG) is considered to be a variant of Activated Tungsten Inert Gas welding. Though Activated Tungsten Inert Gas welding (ATIG) is widely popular among scientific community, it lacks the versatility to be adapted by various industries because of its inherent demerits.

Modeling, optimization and classification of weld quality in tungsten inert gas welding
International Journal of Machine Tools and Manufacture, 1999In this paper, a neural network is used to construct the relationships between welding process parameters and weld pool geometry in tungsten inert gas (TIG) welding. An optimization algorithm called simulated annealing (SA) is then applied to the network for searching the process parameters with an optimal weld pool geometry.

Mutation Research/Genetic Toxicology, 1995
Cytogenetic damage was studied in lymphocytes from 23 welders using the Tungsten Inert Gas (TIG), and 21 welders using the Metal Inert Gas (MIG) and/or Metal Active Gas (MAG) methods on stainless steel (SS). A matched reference group I, and a larger reference group II of 94 subjects studied during the same time period, was established for comparison ...
