Effect of Tool Pin Profile on Friction Stir Welding of Dissimilar Materials AA5083 and AA7075 Aluminium Alloy

Effect of Friction Stir Welding on Mechanical Properties of Dissimilar Aluminium Alloys

Friction stir welding is advance joining process for different similar and dissimilar metals. It is commonly used for joining of Aluminium alloys. In this study an attempt were made to join commercial structuralaluminium with 7039 aluminium alloy. A zig-zag pattern of hardness was found in weld nugget. Microstructural characterization and fractography of joints were examined using optical and s...

Friction Stir Welding of Dissimilar Materials: An Overview

Effect of Tool Shoulder and Pin Cone Angles in Friction Stir Welding using Non-circular Tool Pin

In friction stir welding frictional heat is generated by the rotating tool, sliding over the stationary plate along the weld centre. Tool being the only source of heat producing member, its geometrical design influences the heat generation rate. In this present work, effects of variation in tool shoulder and tool pin taper angles on thermal history during joining are analysed. Tools with triang...

Effect of tool position on microstructural and mechanical properties of friction stir butt welded joint of AA2024–AA7075 dissimilar alloys

In this research, butt joining of Al2024 and Al7075 plates were performed by Friction Stir Welding (FSW) and the effect of tool position on microstructural and mechanical properties in about 1 mm from center line of joint towards the advancing side (AS) and the retreating side (RS) was investigated at three positions of +1, 0, -1 mm. In this regard, the plates of Al2024 and Al7075 were selected...

Analytical Investigations of the Effects of Tool Pin Profile and Process Parameters on the Peak Temperature in Friction Stir Welding

In this work, effects of different tool pin profiles of flat and tapered shoulder geometries on the peak temperature in friction stir welding are investigated analytically. The developed models used for the analytical investigations considered the welding process as a combination or mixture of the pure sliding and the pure sticking. From the results, the amount of heat generation and the peak t...
