摘要：

The heat input to the tool has been characterized at a variety of operating parameters for bead-on-plate friction stir welding (FSW) of AL 7075-T7351. In a statistical Design of Experiments (DOE) fashion, 54 welds were performed at 27 parameter combinations. During each of the welds the heat flow through the tool was calculated based on infrared imaging temperature measurements. The percentage of the total mechanical power required for FSW that enters the tool was also determined. For the range of operating parameters and the tool used, the heat input to the tool ranged from 155 W to 200 W, comprising 2.8% to 5.1% of the total mechanical power. Regression equations developed for the two values show that each is a function of the process operating parameters.
