Friction Stir Welding, a relatively new welding process, was developed in 1991 at The Welding Institute near Cambridge, England. In this process parts are mated together, rigidly fixtured, and joined in solidstate by forcing a rotating tool into the joint, and traversing that tool along the joint. This process creates weldments with properties comparable to the base metal, and in most cases superior to traditional fusion welding techniques. This is a solid state joining process, which is currently being developed for difficult to weld high strength aluminum alloys (e.g. the 2xxx and 7xxx series). This new technique is being successfully applied to the aerospace, automobile, and shipbuilding industries, and is attracting more and more research interest. In FSW the temperature distribution is very important parameter, in order to see that the materials being welded are not melted and the joining of the materials is taking place successfully. A good understanding of the heat transfer process in the workpiece can be helpful in predicting the thermal cycles in the welding workpiece, and the hardness in the weld zone, subsequently, can be helpful in evaluating the weld quality. An attempt is made to find the temperature distribution in FSW fleet through experimentation.

Abstract


Friction Stir Welding, a relatively new welding process, was developed in 1991 at The Welding Institute near Cambridge, England. In this process parts are mated together, rigidly fixtured, and joined in solidstate by forcing a rotating tool into the joint, and traversing that tool along the joint. This process creates weldments with properties comparable to the base metal, and in most cases superior to traditional fusion welding techniques. This is a solid state joining process, which is currently being developed for difficult to weld high strength aluminum alloys (e.g. the 2xxx and 7xxx series). This new technique is being successfully applied to the aerospace, automobile, and shipbuilding industries, and is attracting more and more research interest. In FSW the temperature distribution is very important parameter, in order to see that the materials being welded are not melted and the joining of the materials is taking place successfully. A good understanding of the heat transfer process in the workpiece can be helpful in predicting the thermal cycles in the welding workpiece, and the hardness in the weld zone, subsequently, can be helpful in evaluating the weld quality.
