ABSTRACT

Advanced lightweight materials are considered as a backbone for any transportation industries to improve the fuel economy, performance and safety. The multi material concept including light hybrid materials is now the buzz word in automotive industry. The areas like body structure of the automobile and power train demands the joining of dissimilar materials. In the present work, an attempt was made to join 6mm thick aluminium 6063 to pure copper using an autogenous friction stir welding process. Four experiments were conducted by varying welding speed at two different values using two non-consumable rotating tools having square and cone shaped pin profiles. The specimens were tested for its quality using visual and radiographic non-destructive testing method. The welded specimens were also tested for its impact strength and hardness. The joints prepared by cone shaped pin at 20 mm/min had a continuous tunnel like defect and lead to poor weld. On the other hand the square pin tool had produced defect free good quality weld. Impact test results showed that impact strength of the welded specimen had directly proportional relationship with welding speed for both tools. Square pin tool had produced better impact strength than cone pin tool by means of effective stirring of the workpiece materials.
