A Comparative Study of Friction Stir Welding and Friction Stir Scribe Welding for Dissimilar Metal Joining

Abstract

Friction stir welding (FSW) has emerged as a novel method for joining similar and dissimilar ferrous and non-ferrous materials. This solid-state welding process utilizes frictional heat generated between a tool shoulder and the base material. The stirring action facilitates the movement and consolidation of the material, resulting in localized fusion and the formation of a joint. This review paper examines the effectiveness of FSW joints through various experimental investigations, considering multiple variables. Furthermore, it explores the application of scribed tool FSW as a recent advancement in the field of joining materials. The review draws upon existing literature to analyze the factors influencing the quality of FSW joints and presents the results of weld quality investigations.
