Friction Stir Welding of High Density Polyethylene

In this report, the progress attained in the Friction Stir Welding (FSW) on polymer project is depicted, evaluated, and discussed. FSW is a derivative of friction welding which uses a solid state joining process relying on the conversion of frictional energy into thermal energy to melt the joint....
