Experimental Investigation of Friction Stir Welding of Aluminium Alloys Using Response Surface Methodology
Journal Title: Scholars Journal of Engineering and Technology - Year 2016, Vol 4, Issue 1
Abstract
Abstract: Friction stir welding (FSW) uses a non-consumable tool to produce frictional heat in the adjoining surfaces. The welding parameters like rotational speed, welding speed, tool pin length, and tool shoulder diameter play a major role in deciding the joint properties. In this work, an attempt has been made to analyse the effect of various tool profiles have been used to fabricate joints by using constant thickness (3mm) work piece of aluminium alloy. The mechanical properties of welded materials are measured in terms of tensile strength. With the help of vertical milling machine create the specimen by friction stir welding (FSW). Now using universal testing machine on which tensile testing of the welded specimen was carried out. After that by using design of experiment (DOE)concept. Experimentally were carried out to predict tensile strength of the welded joint. After comparison of predicted and practical values of tensile strength conclude that with increase in pin length tensile strength increase contently and tool geometry with a large shoulder diameter together with high welding speed leads to decrease in welds speed leads to decrees’ in tensile strength of the welds work pieces. Keywords: aluminium alloy 6063-TS, friction stir welding, RSM.
