istory
Friction Stir Welding was invented at 2W3 (The Welding
Institute), England in the year 1991.
Friction Stir Welding is a solid-state rocess, in which the
o!"ects are "oined !elow the #elting oint with the hel o$
ressure.
%eating !y the $riction !etween rotating tool and wor&
iece.
The heat generated in the "oint area is tyically a!out
'-9 o$ the #elting te#erature.

Conc"usion
The seci$ied contours o$ te#erature distri!ution are generated so we canesti#ate the te#erature at that articular and its near!y that locations.
The velocity distri!ution o$ #etal $low near the weld nugget is also so#ewhat
revealed.
Te#erature contour also oints out that the te#erature distri!ution at
advancing side and retreating side is di$$erent. Te#erature gradient contour on a horiontal lane has revealed the
te#erature ro$ile !e$ore and a$ter welding oeration.
Te#erature distri!ution and #otion o$ te#erature ro$ile is revealed.
0o#arison o$ eeri#ental and analytical result data shows that 1-5
variation in te#erature occurs in :nsys data and Eeri#ental data.
Te#erature distri!ution at any instant o$ ti#e erendicular to weld line can
!e &nown $or any location.
