Simulation of Temperature Distribution in TIG Spot Welds of(Al-Mg) Alloy Using Finite Element Method

This research concern to analyse and simulate the temperature distribution in the spot welding joints using tungsten arc welding shielded with inert gas (TIG Spot) for the aluminum-magnesium alloy type (5052-O). The effect of and the quantity of the heat input that enter the weld zone has been inves...
