Thermo-Mechanical Analysis in TIG Welding of Aluminium Alloy 6082
Journal Title: UNKNOWN - Year 2015, Vol 4, Issue 4
Abstract
Tungsten Inert Gas (TIG) welding has been widely used for the fabrication of various structures made of metals because of its high weldment. TIG welding is versatile and having less loss of alloying elements which can be protected from the atmosphere by an inert gas such as Helium, Argon and mixture of Helium and Argon. The objective is to study the variation of temperature in TIG welded plate of 5mm work piece thickness. Based on the experimental records of temperature at specific locations during the TIG welding process, Thermo - Mechanical simulation is developed. Comparison with the temperature measured by the thermocouples records shows that the results from the present simulation have good agreement with the test data.
