Friction stir welding

In the present work, a novel tube-tubesheet seal welding method using friction stir welding (FSW) and experimental setup was developed. The development involved a number of design and manufacturing aspects such as, tool and fixture design, and FSW process parameters. The influen…

Friction stir welding (FSW) is a well recognised method for joining aluminium alloys and other engineering materials at a temperature below their melting point. However, the microstructure of the alloys may be modified during the welding process due to frictional heat and severe…
