A REVIEWS ON THE FRICTION STIR WELDING PROCESS THAT AFFECTS VARIOUS PARAMETERS
FRICTION STIR WELDING
A friction stir welding (FSW) is clearly an important process for the success of welding. Many common problems of fusion welding are overcome by friction stir welding (FSW), a widely used solid state joining process for soft materials such as aluminum alloys. The commercial achievability of the FSW process awaits the expansion of cost-effective and durable equipment for rigid alloys such as aluminum that lead to structurally sound welds. Material assortment and design significantly affect weld quality and cost. In this review several important aspects of FSW equipment such as equipment material selection, geometry and load carrying capacity, thermal behavior, equipment reduction mechanisms and process economics.
