ASSESSMENT OF FRICTION STIR WELDING: AN OVERVIEW

초록

Friction stir welding (FSW) has an advanced technique in solid-state conditions that joins from different materials compared to the fusion welding process and is eco-friendly. This significant advancement involves aluminium (Al) alloys which facilitate the FSW of distinguished flow patterns in the weld zone. Technically, heat energy and stirred material resulted in softening areas, affecting joint efficiency, mechanical properties, and metallurgical characterisation. This paper has concerns comprehensively covering and summarising the development and application of the topic in different aspects of the performance and quality of the FSW welded joint. The proper tools can create sufficient heat under the shoulder for excellent performance to deal with the welding parameter. All these tools have their literature and journal, which extensive discussion.Furthermore, alloy positioning, defect formation, rotational speed and transverse feed are essential analytical tools for FSW to control the significant weld quality. Furthermore, the mechanical properties associated with microstructural evolution highly dependent on welding technique have remarkably contributed to product development. Finally, a previous study has shown the interest in the topic to enhance the knowledge for further investigation with emerging technology for future recommendations in the FSW discipline.
