Friction stir welding is a solid state welding process suitable for producing joints, especially in lightweight materials, which are particularly interesting due to the weight saving potential. The plunging of a specially designed non-consumable and rotating tool creates a connection between the sheets through frictional heat and plastic deformation. Minimum material loss is observed, and therefore a fully consolidated joint with flat surface is obtained. The aim of the present work is to investigate the mechanical properties of butt joints produced by friction stir welding (FSW) in high density polyethylene sheets of 6 mm thickness. The mechanical properties namely tensile strength and bending strength tests were carrying out on welded specimens. The results obtained were compared with parent materials strength, it is observed that polyethylene sheets could be Friction Stir welded with joint characteristics similar to base material. This could be accomplished by operating with a high rotational speed. in addition parameters such as rotational speed, plunge depth and dwell time on polyethylene joints were investigated
