Welding is a suitable and better process to manufacture complex objects for aerospace, naval, automotive structures. Service conditions complexity in load acting force the manufactures make joints between dissimilar materials. Thus, there need efficient welding techniques form sound an understanding of imperfections their effects. In this study attempt has been made joining feasibility aluminum...

Friction Stir Processing (FSP) is a method for solid-state processing, in which rotating tool moved onto the material surface to modify microstructure and thus obtain improved properties of surface. We study effects FSP on aluminium alloy A6061-T651 using made at Institute Metal Science, Equipment, Technologies with Centre Hydro- Aerodynamics (IMSETCHA) Bulgarian Academy Sciences. The has threa...

The present study focuses on development of mechanical characteristics in ultrasonic vibration assisted friction stir welding (UAFSW) AA 2014-T651 weldment using graph theory algorithm and utility concept. A set UAFSW experiments were carried out plain taper threaded cylindrical tool pin profile weldments at different levels rotation speed traverse experimental results for the tensile strength,...

The vibration in the milling process plays a key role machining, which can significantly affect machining quality of workpiece. Some vibrations have negative influences on workpiece surface, while other improve stability. Therefore, it is critical to distinguish influence different types quality. A simulation method undeformed chip thickness considering presented this article, finite element mo...
