Study The Influence of Process Parameters on Weld Quality and Perform Formability Test Sumer Singh College of Technology and Engineering, Udaipur --------------------------------------------------------------------------***----------------------------------------------------------------------Table 1.1 FSW tool dimensions. Introduction- In current automotive stamping technology, there are two basic paths that can be followed to arrive at the final panel. The first method is part disintegration. In this technique, each different section of the blank is stamped separately and then spot welded together in the shape of the final part. This method has numerous advantage such as the ability to select the specific properties, i.e. the strength, thickness, corrosion resistance etc of each area of the blanks. This method also gives a higher yield ratio of material used. However, this method has some disadvantage. The major problem is the large number of different forming operations that is required for the disintegration method, which translate to high tooling costs. Also assembly costs would increase (more joining required) and there is possibility of fittability problem between the different stamping. The other possible method is the integration method. In the integration method, the part is stamped out of a single blank. This reduces the number of tools needed; the assemblies cost and eliminate the fittability problem. However, the design engineer is forced to work same grade, thickness, strength and corrosion resistance throughout the entire part; this would increase the cost and weight of the part significantly.

1.1 Friction Stir Welding Setup: The following were used for the Friction Stir Welding Process of Aluminium alloy sheets. 1. 2. 3. 4. 5. 1.
2. Backing Plate: A plate of dimensions 200 x 100 x 10 mm was firstly cut by hacksaw machine then machined on shaper in order to reduce the thickness to 8 mm and later the finishing process was carried out on surface grinding machine. The flatness of the backing plate is a crucial factor in order to perform the experiment correctly.
Vertical Milling machine Fixture Backing Plate Tool Specimen Fixture: A fixture is a work-holding or support device used in various manufacturing processes. The main purpose of a fixture is to locate and in some cases hold a workpiece during a machining operation.
