Description
Summary:Welding process is in high demand, which required a competitive technology to be adopted. This is important for sustaining the needs of the joining industries without ignoring the impact of the process environment. The quality of Bobbin Friction Stir Welding (BESW) is depending on the material stirring by the tool and fixture. Bobbin Friction stir welding (BFSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join the high-strength aluminum alloys and other metallic alloys that are hard to wel by conventional friction stir welding (CFSW). BFSW is considered to be the most significant development in metal joining in a decade. In this review article, the current state of understanding and development of the BFSW are addressed. Particular emphasis has been given to: (a) to quantify vibrationgenerated from different fixture design of BFSW. (b) To investigate the impact of vibration on weld formation and weld strength through mechanical test and (c) To suggest the suitable fixture design of BFSW using design of experiment approach. Using Taguchi with factorial model in order to identify the correlations between response parameters and the total of 9 experiments were conducted. The problem was vibration was a major problem during the production process and greatly affects the quality of the product strength. The result collected was optimized using Taguchi and p-value and R-square were calculated using analysis of variance (ANOVA). According 10 the result Design C is the best design fixture that indicate 25 mm of shoulder gab with 17.5978 mm/s of vibration velocity, 32.0167 HRH of hardness value and 77,1598 Mpa of tensile strength value.
