Abstract:

Over the last twenty years Friction Stir Welding (FSW) has proven to be a very promising new joining technique. Especially high strength aluminium alloys can be welded with large advantages as compared to conventional fusion welding processes. Friction stir welding (FSW) of aluminium components using both fixed and variable gap bobbin tools has been demonstrated by several researchers, and reportedly these procedures were relatively easy to develop. Bobbin welds do not have an initial phase where the welding tool probe is plunged axially into the work piece as is done in conventional FSW. Bobbin welds are typically started by driving onto the edge of the plate or from a pre-drilled hole with an initially slow travel speed until plastic deformation starts, followed by acceleration of the travel speed to the final steady state value. The objective of current paper is to examine and summarize information for change in mechanical properties for bobbin tool friction stir welding (FSW) for joining materials. The findings presented, friction stir welding (FSW) with bobbin tool and parameter involved in it understand.
