Abstract

This paper reports on a study aiming at comparing mechanical and structural properties of Ti6Al4V titanium alloy of grade 5 welded by TIG and MIG welding. To achieve this motive titanium alloy plates of thickness 5mm were welded using tungsten inert gas welding (TIG) and metal Inert gas welding (MIG). Mechanical properties, microstructure, residual distortions and welded geometry of the joints produced with TIG and MIG welding were analyzed. TIG and MIG are generally two most commonly used welding on titanium alloy (Ti6Al4V). Welding is done by using filler material ERTi5. Tn all 18 specimens were tested for determining different properties of titanium alloy out of which 9 specimens were welded using TIG welding and the other 9 by using MIG welding. At the specimens were welded at different welding parameters such as by varying current, voltage, gas flow rate, depth of weld, welding speed, etc. and after testing each specimen for various mechanical properties results are obtained. Taguchi methodology was used to conduct the experiments and analysis of results obtained from welded joints.

Keywords
