Description
Summary:Friction Stir Welding (FSW) is a solid-state joining process that involves joining of metals without fusion or filler materials. The process is particularly applicable for aluminum alloys but can be extended to other products also like steels. The project was mainly founded by National Technological Agency of Finland. The friction stir welded joints of austenitic and ferrite stainless steels were implemented at different rotational speeds 500 ∼ 1100 rpm. The results showed that increasing rotating speed enhanced heat input and material movement in the welded zone, and the nugget zone had a blocky, laminated, and vortex structure of austenite and ferrite. In this investigation, different combinations of tool rotation speeds and tool transverse speeds are used to connect different types of stainless steel. Following an overview of the macroscopic characteristics, the micro structure development and associated hardness tensile and impact results and distributions are discussed.
