Research on Friction stir welding using Taguchi method

When compared to conventional welding techniques reported in the literature, the friction stir welding process is an advanced welding technique that offers numerous advantages. In a brief, the advantages: 1. Good weld quality 2. Power consumption is decreased 3. No flux or filler material, etc. This FSW process is considered as the research project because of its advantages and the growing popularity of the FSW process in various automobile and aerospace industries. The effects of process parameters such as tool rotational speed, weld speed, and tilt angle on the responses and tensile strength in dissimilar welding of Aluminum alloys of various grades utilizing the solid-state welding technique Friction Stir Welding are reported in this work. The weld joint was tested for ultimate tensile strength (UTS) and Brinell harness number (BHN). Taguchi method was used to obtain the optimum process parameters and then ANOVA test was carried out to find the contribution and most significant process parameter effecting the ultimate tensile strength and Brinell hardness number.
