The effects of transverse welding speed of the tool on the mechanical Received in Revised form properties and microstructure of the joint were studied experimentally. By examining different October 14 2013 circumstances changes in the joint strength were studied and optimized in term of transverse Accepted 27 February 2014 Available online speed. Based on the obtained results welding speed can improve or reduce the joint strength 12 March 2014 and an optimum value can be found for the welding speed. Welded Joint that was conducted at Keywords the rotation speed of 800 RPM and tool traverse speed of 60 mm min 1 had the highest tensile Friction stir welding strength . about 98 of the weak base metal . Intermetallic compounds were formed in the Dissimilar Al-Cu joint stir zone and XRD results indicated that Al4Cu9 and Al2Cu were the intermetallic compounds in Intermetallic compounds the stir zone. Micro-cracks formed around the intimatelic particles were observed in the section Microstructure of joint. Tensile strength Transverse speed 2014 Growing Science Ltd. All rights reserved. 1.
