Abstract:

Finite element simulation is utilized in an aluminum alloy 2014 butt weld with the three kinds of welding processes, namely the filler wire Tungsten Inert Gas (TIG) welding, the laser welding and laser-TIG hybrid welding. The simulated results are in good agreement with the weld cross sections for the TIG and the laser welding, and basically in agreement with that for the laser-TIG hybrid welding using the actual welding parameters. Furthermore, the simulated results shown that the longitudinal residual stresses after welding are the largest for the laser welding and the laser-TIG hybrid weldi

Abstract:

Activated Tungsten Inert Gas (A-TIG) welding with deeper penetration characteristic than manual Tungsten Inert Gas (TIG) welding is one of developed TIG welding processes for higher welding productivity. However, underfill phenomena often occurs when A-TIG welding applies to butt joints of Stainless steels with gap and misalignment. In order to complete welding, additional welding passes are needed. To prevent the underfill phenomena, A-TIG welding using semi-automatic cold wire feeding process can be one of alternatives. In this study, semi-automatic cold wire feeding condition for sound A-TI

Tungsten inert gas welding (TIG) is more stable and allows for more precise control than most other arc welding processes. TIG welding is desired in the aerospace sector when thin parts have been welded with accuracy. However, when welding thick sections, autogenous TIG welding is not commonly recommended due to the limited depth of penetration required. It is in effective for joining the thick parts in a particular pass. Welding with activated flux tungsten inert gas (A-TIG) enhances weld penetration by four times in a single pass.

Abstract A comparative evaluation of the influence of welding current on Tungsten Inert Gas (TIG) welding and Activated Tungsten Inert Gas (ATIG) welding on the depth of penetration and microstructure properties was performed. Various super duplex stainless steel (SDSS) beads on plate weld joints were studied. Visual observation showed that lower welding current resulted in partial weld penetration in the case of both TIG and ATIG weldments. Weld joints obtained by the ATIG process have a higher depth of penetration and depth/width ratios than weld joints obtained in the conventional TIG proce

AbstractA comprehensive investigation was conducted into the effect of oxides on penetrations, microstructures and mechanical properties of BS700MC super steel weld bead. Boron oxide changed the penetration of weld bead by changing the Marangoni convection in the weld pool and contracting the welding arc. Chromium oxide only changed the Marangoni convection in the weld pool to increase the penetration of super steel. Thus, the super steel weld bead has higher penetration coated with flux boron oxide than that coated with chromium oxide. In other words, the activating flux TIG (A-TIG) welding w

Abstract Ferrous alloys are employed in a range of fields, including aerospace, construction, automobiles and chemical processing. One of the most used welding processes for the fusion of ferrous metals is gas tungsten arc (GTA) welding or Tungsten Inert Gas (TIG) welding. Due to the lower amount of penetration accomplished using only one pass, welding is less frequent in some industrial situations. Fluxes have been discovered to improve the penetration depth of GTA welding, resulting in increased productivity. The research on Activated flux induced TIG (A-TIG) welding of ferrous alloys is dis

The width of the heat-affected zone welded by laser-TIG welding process was obviously narrower than that of welded by TIG.

Abstract:

Tungsten inert gas (TIG) is currently one of the most widely applied welding technologies. However, the arc energy divergence and high heat input of conventional TIG can lead to welding defects in heat-input-sensitive alloys (such as Inconel 718). Introducing a fast-frequency pulsed current (≥20 kHz) in TIG creates a welding process named fast-frequency pulsed tungsten inert gas (FFP-TIG). The arc behavior of FFP-TIG has advantages over conventional TIG in terms of arc contraction, arc pressure, and energy density. With an increase in the FFP current amplitude or frequency, the arc diameter an
