Friction welding is one of the higher state, economical, highly productive method used to join different metallic materials. Advantages of this welding are low production time, high material save. It is also possible to join circular as well as rectangular cross sections. In friction welding joining occurs below the melting temperature of the work piece. The dissimilar metal joint of Titanium and 304 Stainless Steel is essential in the nuclear industry for the dissolution of spent fuel that is carried out boiling nitric acid in the dissolved solution. Welding dissimilar materials makes use of advantages of different materials to unique solutions, like combination of good mechanical properties such as specific weight, corrosion resistance etc.
In this project, Friction welding is carried out on two dissimilar materials such as 304 Stainless Steel and Titanium grade 5. Welding is carried out by varying different parameters such as spindle speed, upset pressure, upset time and subjected to mechanical testing such as tensile and hardness to study the effect of welding parameters. Further microstructure of the flash is examined through optical microscope.
