Abstract
This work is an attempt to study the feasibility of the friction stir spot welding (FSSW) of the sandwich sheet with honeycomb core and examine the effect of rotational speed on plunge load, torque, and lap-shear test performance. While keeping all other parameters constant, the plunge load decreases with the increase in the rotational speed of the welding tool, whereas welding torque increases as the rotational speed of the tool increases. The lap-shear test fracture load increases with rotational speed and the maximum fracture load of 1338 N is obtained at 462 rpm, and nugget pull-out failure and shear failure have occurred at the lowest and highest rotational speeds, respectively.
