This paper presents the results obtained by numerical simulation regarding springback phenomenon of a U-shaped part manufactured from tailor welded stripes. The final shape of the formed part is seriously affected by springback phenomenon. This paper work is trying to prove the important role the metal sheet thickness on the springback effect. The U-shaped part has different springback values f...

The purpose of this study was to develop a specialized Friction Stir Welding process for superplastic grade aluminum alloy 5083-SP and titanium alloy 6Al-4V, in thickness of 1.5 to 4 mm, such that the butt welded nugget would have equal superplastic forming (SPF) characteristics as the parent sheet material The concept of using tailored blanks for the SPF process is proposed which will allow th...

This paper refers to some simulation tests concerning the formability and springback of a U-shaped part manufactured from tailor welded stripes. The final geometry of the obtained part is seriously affected by springback phenomenon. This paper work is trying to prove out the important role samples dimension has on the springback phenomenon. The influence of the samples width on the tailor welde...

This paper deals with some numerical simulation and experimental tests related to forming and springback of a rectangular part manufactured from tailor welded blanks. Final shape of the parts manufactured by tailor welded blanks is seriously affected by springback effect. This paper work is trying to prove out the important role of material rolling direction has on the springback reduction. The...

Abstract In this study, in order to obtain the maximum possible formability tailor-welded blank AA6061 sheets connected by friction stir welding (FSW) procedure, incremental sheet forming process has been utilized. The results are presented both numerically and experimentally. To limit angle, base FSWed were formed different angles with conical geometry, ultimately, angle for metal is estimated...

Currently there is a huge competition amongst the OEMs and manufacturers in the auto industry to reduce the weight of the car. A few design modifications or use of different size and grades of materials solves this problem greatly. This paper focuses upon the metal finishing process of Laser Welded Blanks (LWB) with simulation and reliability as well as new process development. These blanks are...
