Friction Stir Welding Technology

The dissertation aims to research the application status and prospect of friction stir welding technology in the theoretical aspects as well as the reality.This paper also focuses on the previous studies,background knowledge and academic theories development related to this area,its application and the difference of understanding it,from the viewpoint of previous researchers.It shows up some resistance and difficulties in analysis,designing and employing friction stir welding technology in the fields of its practical application.The researcher conducts quantitative research methods and observation in the experiments.The study is also based on the designing of the model which could show the application status and prospect of friction stir welding technology and definitely indicates the theories and formula.Clear data from the previous studies and the process of experiments will be applied to show the conclusion clearly.Moreover,some significant data and hypothesis which the researcher adopted from the background knowledge and academic reading will be analyzed by using methods for example reliability test,experiment test.The friction stir welding is also used for the welding of a variety of light metal alloys and non-metallic materials.The welding materials,the structure of weld joints,the mechanical properties of friction stir welds,the welding procedures and the welding tools are discussed.
