Observation of different experimental parameters effect using friction stir welding through simulation of tailor welded blanks

Abstract

In the present scenario, the industries of automobile are focusing in decrease in the weight of the automotive body by using which we can increase the efficiency of fuel orally. Many researchers are working keeping this as motto, many joining techniques and engineering materials are used to decrease the decrease in weight for increasing the fuel efficiency. By synchronizing this, there is a technique called tailor welded blanks (TWB) is recommended highly by many automobile industries and researchers have been chosen this technology. In the current work, the motto is the behavior of forming in the TWBs using the process of friction stir welding (FSW) in two welding speeds (90 mm/min and 100 mm/min). The simulations of forming were conducted using the test called limiting dome height (LDH). Eight strain paths were considered for the simulation with maximum size of 200×200 mm to minimum size of 25×200 mm. The base metal Forming limit diagrams, the sheets of FSW are plotted and compared. From the results of simulation, it has noted that base material has lesser formability than FSW sheets. At 100 mm/min welding speed, FSW sheet fabricated and has noted increasing the formability than the welding speed of FSW sheet at 90 mm/min.
