Experimental Investigation of Friction stir Welding on Ultra High Molecular Weight Polyethylene
Keywords:
FSW, UHMW-PE, Welding Speed, Tool pin lengthAbstract
Friction stir welding (FSW) is a solid state joining technique that is widely used for joining materials which
are difficult to join with traditional fusion welding in many application of commercial importance. This process is
considered as "Green Technology" due to its energy efficiency, environment friendliness and versatility. In recent years,
FSW is employed for welding of polymers and its composites. Friction stir welding parameters affect the weld strength of
thermoplastics, such as Ultra High Molecular Weight Polyethylene (UHMW-PE) sheets. The effect of welding
parameters on tensile strength of friction stir weld of UHMW-PE were investigated. For joint formation and maximum
tensile strength tool rotational speed, welding speed and tool pin length were determined to be important.
