Effect of welding speed on microstructures and mechanical properties of underwater friction stir welded 2219 aluminum alloy

Underwater friction stir welding (underwater FSW) has been demonstrated to be available for the strength improvement of normal FSW joints. In the present study, a 2219 aluminum alloy was underwater friction stir welded at a fixed rotation speed of 800 rpm and various welding speeds ranging from 50 t...
