In this paper, study of heat generation during friction stir processing of similar joints of AA6061-T6 is carried out. A three dimensional (3D), transient, non-linear thermal model was developed using ANSYS 16.2 software to simulate the heat generation profile during Friction Stir Processing of similar Aluminum plates. The results showed that the observed temperature rise in the model shows that heat generation during the second and third load steps is due to friction between the tool shoulder and work piece, as well as plastic deformation of the work piece material. It was also observed that friction is responsible for generating most of the heat needed, while the contribution of heat due to plastic deformation is less significant. Because the tool-penetration is shallow and the tool pin is ignored, the plastic heat is small compared to frictional heat.
