Abstract

The friction stir welding technique is a derivative of conventional friction welding, which enables the advantages of solid-phase welding to be applied to the fabrication of long butt and lap joints, with very little postweld distortion. Friction stir welding is a remarkable new welding technique for joining aluminum alloys and has the potential for welding other ferrous materials. It has already been developed beyond a laboratory curiosity and has been proved as a potential practical welding technique offering low-distortion, high-quality, low-cost welds from simple concept machine tool welding equipment. To bring this remarkable method of welding aluminum alloys to the attention of Industry, this article introduces the basic principle of friction stir welding, pointing out the practical advantages and most important of all, describes the exceptionally good metallurgical and mechanical properties.
