In the present research, weld pool geometry, thermal cycle, temperature and velocity fields during gas tungsten arc welding of aluminum alloys. Much research has been conducted on heat and mass transfer [1][2] [3], fluid flow [4,5] and weld pool formation [6,7] in ordinary arc welding technologies, such as Gas-tungsten.

An improved process for Gas Tungsten Arc welding maximizes the depth/width ratio of the weld pool by adding a sufficient amount of a surface active element to insure inward fluid flow, resulting in deep.

Gas tungsten arc welding Tungsten Electrode 2%La, mm Ø, 30° tip parameters were: A (20 ms), 60 ( ms), 2 mm arc gap, Arc Gap 2 mm mm/s, and helium shielding gas.

This was done on 4 mm Shielding Gas 28 L/min, Helium thick aluminum plate to produce partial penetration welds of approximate 6 mm diameter. Arc Welding: GHTAW and Pipe Welding Previous simulations of arc welding processes generally adopted the axis-symmetry arc heat flux model [1].

These studies, however, do not consider the effect of various conditions such as ambient pressure and joint shape, which can deform the arc plasma characteristics. On the assumption of linear additively of strength contributions, good agreement between calculation and experiment has been found for the flow stress of IF steel [10], nickel [7] and aluminum [6] and for the flow stress anisotropy in IF steel, aluminum and copper [21].
