Simulation of flow stress, temperature and pressure on friction stir welding of edge joint on similar aluminium alloys 6061

Friction stir welding process is used for joining material such as Aluminium, copper, magnesium etc., which are otherwise difficult to weld by the conventional welding processes. The tool pin profile plays a critical role in determining the end properties of the welding joint apart from other parameter like rotation speed, traverse speed, welding speed, and axial load. The purpose of the investigations was to elaborate a set of FSW parameters for connecting 6061 aluminium alloy sheets allowing to produce welds of highest strength. The results of present experiments are adding new information on FSW of the aluminium alloys, especially 6061 type. The applied welding parameters provide good quality of welds. The aim behind. In analysis we use AA6061 similar material for flow stress, temperature and pressure analysis with Hyper works 9.0
