TIG and A-TIG welding experimental investigations and comparison to simulation
Science and Technology of Welding and Joining, 2012In the present work, the chemical mechanism was shown for tungsten inert gas (TIG) and active TIG (A-TIG) welding. The results obtained with a two-dimensional axial symmetric model developed to simulate the flow behaviour in the meting pool on a stainless steel disc (304L) melted by a stationary heat source were presented to show the influence of ...

TIG and A-TIG welding experimental investigations and comparison with simulation
Science and Technology of Welding and Joining, 2012In this part II, the comparison of physical mechanisms between tungsten inert gas (TIG) and active TIG (A-TIG) welding is shown. The plasma was monitored by a high speed camera to present the arc constriction phenomena while passing from TIG to A-TIG.

Improvement in Depth of Weld Penetration During TIG, Activated-TIG, and Pulsed TIG Welding
International Journal of Manufacturing, Materials, and Mechanical Engineering, 2021Joining of dissimilar materials has gained a lot of interest in the recent years due to the increased demand of high strength and light weight designs. Fusion welding plays a vital role in repairing and manufacturing industries like automobile, construction, ship building, and energy sector.

Abstract Hastelloy C-276 is a nickel-based alloy with high strength and corrosion resistance at cryogenic to high temperatures. The issue of Hastelloy C-276 shallow penetration by Tungsten Inert Gas (TIG) welding was addressed in the current investigation by applying A-TIG welding with variable oxide flux.

Pulsed TIG Welding of Aluminum
Welding International, 1990As a consequence of developments in the electronic control of welding power sources, there has been a trend for even inexpensive and widely used metal inert gas (MIG) and tungsten inert gas (TIG) welding machines to be equipped, as standard, with a high performance pulsed current waveform control function.
