Abstract
In spite of considerable interest in Friction Sir Welding, there has been little published information about the workpiece temperature field during welding. This paper reports temperature measurements made with embedded thermocouples during welding of 6061 aluminum. An intuitive model, similar to Rosenthal's moving point source solution, has been developed to quantitatively correlate the temperature field in Friction Stir Welding to basic process variables. Good agreement between the model and the experiment has been obtained. Microstructures within the weld zone are characterized by dynamic recrystallization, grain growth, and complex aging phenomena which show no evidence of melting. These observations are consistent with maximum temperatures which do not exceed .8T M.
