Solid state friction stir welding (FSW) on similar and dissimilar metals

Welding is a process which helps to join metals by adding metals between weldments by diffusion process.. One of the process by which metals are joined by creating friction on metals. It is called solid state welding. A rotating hard cylindrical pin is pressed on metals to be welded by friction. In...

The surface roughness Ra value low compared to copper base metal. The Vickers hardness value was high compared to base metal. Aluminum to copper metal joint the best resulted at 2275 RPM. The result was the lowest compared to similar metal joints. The value of 427 MPa of ultimate tensile strength (UTS) was archived. The metallographic test showed that a crack occurred at the bottom of welding joint. The hardness test showed that the hardness at the joint increased drastically.
