Abstract:

The amount of heat generated between the shoulder and the Workpiece during solid-state weld dictates the quality of the processed zone. Since direct temperature measurements of the welded region are not possible, a numerical model was developed to predict the temperature in this area. Hence understanding the distribution of heat and obtaining the temperature contours will assist in understanding the general process of solid-state welding. A three-dimensional finite element model is developed to study the temperature history in the butt welding of AA6061 aluminum alloy using COMSOL software. The variation of temperature with respect to thermal conductivity, specific heat, and density was developed. The predicted peak temperature is used to obtain the temperature contours throughout the Workpiece. The results suggest that the temperature achieved during processing plays an important role in determining the properties of the processed Aluminium alloy.

Keywords:
