Joining of 5083 and 6061 aluminum alloys by friction stir welding

摘要

Friction stir welding (FSW) has emerged as a new solid state joining technique [1], especially for aluminum alloys [2-6]. In this process, a rotating tool travels down the length of contacting metal plates, and produces a highly plastically deformed zone through the associated stirring action. The localized heating zone is produced by friction between the tool shoulder and the plate top surface, as well as plastic deformation of the material in contact with the tool [1].
