چکیده مقاله
The FSW process has emerged as one of the most advanced methods for bonding metals and polymers in the last decade, which has a much higher energy efficiency than other welding methods In this research, the weldability of polypropylene sheets has been investigated by friction welding process FSW , the purpose of which is to determine the optimal process conditions to achieve the strength and surface conditions suitable for bonding samples during welding The concept behind friction welding is the generation of heat at the joint due to friction work and the use of pressure to conduct polymeric materials In this paper, in order to do a scientific work on the effect of pin shape on weld strength and to obtain the best geometry for welding polypropylene parts, Welding was performed with the same dimensions by tools with simple triangular pins, grooved triangles, grooved cylinders and grooved cones After tensile testing experiments performed on welded parts with these tools, a more suitable tool was selected for this process The ideal tool has a grooved conical pin and an Archimedean shoulder and the direction of rotation is also clockwise The reason for this choice was the higher failure stress of this tool, which is 11 34 MPa
