Influence on the Tensile Properties of AA7075-T6 under Different Conditions during friction stir welding process

Abstract

Abstract The main idea is to study the outcome parameters of FSW on finest quality of AA7075-T6. The welding of AA7075 is done by vertical milling machine with using different tools. Different welding parameters are studied on fluctuating tool rotational speed which varies 900 to 1750 (rpm), having tool shoulder diameter between 15 to 20 mm and transverse speed of the table which is under the range of 30 to 45 (mm/min). Taguchi technique is used for optimizing the welding parameters. In this present investigation three factorial and three level designed are used for optimization through the Taguchi Technique. The result which are detected defines that due to increase in rotational speed the tensile strength of welded joint increases and tensile strength decrease due to the frictional heat which is generated during the FSW process.
