Analytical Investigations of the Effects of Tool Pin Profile and Process Parameters on the Peak Temperature in Friction Stir Welding
In this work, effects of different tool pin profiles of flat and tapered shoulder geometries on the peak temperature in friction stir welding are investigated analytically. The developed models used for the analytical investigations considered the welding process as a combination or mixture of the pure sliding and the pure sticking. From the results, the amount of heat generation and the peak t...
متن کاملSimulation of Tool Rotation and Travelling Speed Effects on Friction Stir Welding of Ti-6Al-4V
In this research, the effects of parameters include tool rotational and traverse speeds were investigated on heat generation and material flow during friction stir welding of Ti-6Al-4V alloy with computational fluid dynamics (CFD) method. Simulation results showed that with increasing of tool rotational and decreasing tool traverse speed, the more frictional heat generates which causes formatio...
متن کاملEffect of Tool Shoulder and Pin Cone Angles in Friction Stir Welding using Non-circular Tool Pin
In friction stir welding frictional heat is generated by the rotating tool, sliding over the stationary plate along the weld centre. Tool being the only source of heat producing member, its geometrical design influences the heat generation rate. In this present work, effects of variation in tool shoulder and tool pin taper angles on thermal history during joining are analysed. Tools with triang...
