Designing and Fabrication of Fixture for Friction Stir Welding of Aluminium AA6061 Alloys

The design of fixture plays an important role in Friction Stir Welding process (FSW). Proper designing of a fixture is one of the major solutions to the problems arising during FSW process. FSW of aluminium alloys requires a careful designing of both fixture and welding tool. The fixture should be designed and fabricated in such a way that it is able to bear the high magnitude forces and high temperature during the welding process. In this paper, designing of the fixture is done using SOLIDWORKS 2D drawing. While designing the fixture certain things are kept in mind such as proper spacing is given for accommodation of backing plate and the metal to be welded.
