A Review of Friction Stirs Welding

A Review of Friction Stirs Welding

Through this paper an attempt is made to study and review a special welding technology of friction stir welding (FSW) which is a solid-state joining process. Friction Stir Welding (FSW) is a recent advanced technique, invented by The Welding Institute (TWI) in 1991, that utilizes a nonconsumable rotating welding tool to generate frictional heat and plastic deformation at the welding location; thereby, affecting the formation of a joint while the material is in the solid state. In particular, FSW can be used to join high-strength aerospace aluminum alloys and other high temperature metallic alloys that are difficult to weld by conventional fusion welding method. FSW is considered to be the most significant development in metal joining process in a decade The comprehensive body of knowledge that has built up with respect to the friction stir welding (FSW) of aluminum alloys. This study addresses the current state of understanding and development of the FSW process. The principles of weld formation, welding parameters, design principles, including metal flow and thermal history, before discussing how process parameters affect the weld properties Danail Abdullah"A Review of Friction Stirs Welding" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-1 | Issue-4 , June 2017, URL: http://www.ijtsrd.com/papers/ijtsrd124.pdf http://www.ijtsrd.com/engineering/mechanical-engineering/124/a-review-of-friction-stirs-welding/danail-abdullah

Friction Stir Spot Welding of Aluminium Alloy AA6063

Friction Stir Spot Welding of Aluminium Alloy AA6063

Friction stir spot welding FSSW is a simplest and quick process for joining aluminium alloys of AA6063 . The FSSW it is a different welding for other resistance spot welding. Aluminium sheets used in Aeorospace applications, high speed trains, ship buildings and also automotive industries. By using aluminium alloys we can reduce the weight of the body.in friction stir spot welding FSSW process radial drilling machine was used as a main component for increase Tool speed and Feed. For this FSSW process on aluminium Alloy the spectial friction stir tool is prepared to spot weld. H13 and EN36 material drill bits used as friction stir spot welding tools. By using aluminium alloys increasing the safety performance. FSSW is as solid state welding technique. I this FSSW process the heat generate between friction stir tool and aluminium alloys. By producing this heat we can make a accurate joint. In this joining processby the help of producing heat metal will be method and comes into solid state then the joint will be done. Dr. B.
