“…Previous work on modeling FSW process can be divided into three main categories: pure analytical thermal models; finite element (FE)-based solid thermal and thermomechanical models, and computational fluid dynamics (CFD) models. Since the development of FSW process, numerous research articles have been published on thermal modeling of FSW [2][3][4][5][6][7][8][9][10][11]. Typically, the procedure involves applying a surface heat flux as the sole source heat.…”

Friction stir welding (FSW) is a solid-state joining process, where joint properties largely depend on the amount of heat generation during the welding process. The objective of this paper was to develop a numerical thermomechanical model for FSW of aluminum-copper alloy AA2219 and analyze heat generation during the welding process. The thermomechanical model has been developed utilizing ANSYS Ò APDL. The model was verified by comparing simulated temperature profile of three different weld schedules (i.e., different combinations of weld parameters in real weld situations) from simulation with experimental results. Furthermore, the verified model was used to analyze the effect of different weld parameters on heat generation. Among all the weld parameters, the effect of rotational speed on heat generation is the highest.

“…e plunge stage is subdivided into two stages: it is called the pin-plunging stage before the shoulder contacts with the workpiece, and the rest is called the shoulder-plunging stage. In the CAM, the volumetric heat flux (yellow zone) is assumed to distribute uniformly in the pin volume [32,33], and the concrete distribution characteristics in the pin-plunging stage at different steps are illustrated in Figure 6. e maximum sectional radius r s and the effective pin volume V ep can be calculated as follows:…”

In the conventional analytical model used for heat generation in friction stir welding (FSW), the heat generated at the pin/ workpiece interface is assumed to distribute uniformly in the pin volume, and the heat flux is applied as volume heat. Besides, the tilt angle of the tool is assumed to be zero for simplicity. ese assumptions bring about simulating deviation to some extent. To better understand the physical nature of heat generation, a modified analytical model, in which the nonuniform volumetric heat flux and the tilt angle of the tool were considered, was developed. Two analytical models are then implemented in the FEM software to analyze the temperature fields in the plunge and traverse stage during FSW of AA6005A-T6 aluminum hollow extrusions. e temperature distributions including the maximum temperature and heating rate between the two models are different. e thermal cycles in different zones further revealed that the peak temperature and temperature gradient are very different in the high-temperature region. Comparison shows that the modified analytical model is accurate enough for predicting the thermal cycles and peak temperatures, and the corresponding simulating precision is higher than that of the conventional analytical model.
