Friction Stir Welding (FSW) was invented and patented by The Welding Institute (TWI) in 1991 [1]. The FSW process involves forcing a rotating tool consisting of a protruding pin and larger shoulder into a material, and traversing the tool along the work piece joint. The rotating tool generates frictional heat which causes the material to plastically flow around the tool. The shoulder usually contains a concavity which allows material to flow and produces a forging pressure on the trailing end of the weld. A lot of work is being canned out to measure the most important and substantial longitudinal forces thus generated, being a critical component for proper tool design. In the present experiment an attempt was made to invent a new technique to measure the longitudinal force distribution on a friction stir weld pin tool.

Abstract


Friction Stir Welding (FSW) was invented and patented by The Welding Institute (TWI) in 1991 [1]. The FSW process involves forcing a rotating tool consisting of a protruding pin and larger shoulder into a material, and traversing the tool along the work piece joint. The rotating tool generates frictional heat which causes the material to plastically flow around the tool. The shoulder usually contains a concavity which allows material to flow and produces a forging pressure on the trailing end of the weld. A lot of work is being canned out to measure the most important and substantial longitudinal forces thus generated, being a critical component for proper tool design. In the present experiment an attempt was made to invent a new technique to measure the longitudinal force distribution on a friction stir weld pin tool.
