Abstract
The exceptional properties of Titanium push it for research activities. A perfect and efficient welding of Titanium in similar and dissimilar manner is also a difficult task for manufacturing companies. Although there are so many ways for welding of Titanium but the most reliable method is Tungsten Inert Gas Welding (TIG). This study is based on the TIG welding and main focus is on temperature distribution. The aim of the study presented in this paper is to determine the temperature distribution profile by using effective and reliable method of simulation. Simulation was performed for Titanium-G5 alloy (Ti-6Al-4V), the most commonly used alloy of titanium. The used analysis was “transient analysis”. The concept of “Moving heat source” and “element birth & death model” technique is used to simulate welding Process. An experiment was also carried out on Titanium-G5 alloy (Ti-6Al-4V) for validation of ANSYS results. In this experiment a noncontact thermal image camera was used for temperature measurement. After the experiment and simulation it was found that temperature varies inversely with welding speed.
