In this research work, welding of highly dissimilar aluminum alloy (6061-T6) and titanium alloy (Ti6Al4V) has been carried out using copper (Cu) interlayer with the friction stir welding (FSW) process by varying the tool rotation speed and tool traverse speed. FSW is a welding technique in which the...
